Electrical engineering is an engineering discipline concerned with the study, design and application of equipment, devices and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution and use.
Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission, development of Marconi's law, and a radio telegraph system. He is credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
Sir John Ambrose Fleming FRS was an English electrical engineer and physicist who invented the first thermionic valve or vacuum tube, designed the radio transmitter with which the first transatlantic radio transmission was made, and also established the right-hand rule used in physics.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
Wireless telegraphy or radiotelegraphy is transmission of telegraph signals by radio waves; Before about 1910 when radio became dominant, the term wireless telegraphy was also used for various other experimental technologies for transmitting telegraph signals without wires, such as electromagnetic induction, and ground conduction telegraph systems.
Computer engineering (CE) is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. Computer engineers usually have training in electronic engineering, software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture.
Reginald Aubrey Fessenden was a Canadian-born inventor, who did a majority of his work in the United States and also claimed U.S. citizenship through his American-born father. During his life he received hundreds of patents in various fields, most notably ones related to radio and sonar.
Andrew James Viterbi is an American electrical engineer and businessman who co-founded Qualcomm Inc. and invented the Viterbi algorithm. He is currently Presidential Chair Professor of Electrical Engineering at the University of Southern California's Viterbi School of Engineering, which was named in his honor in 2004 in recognition of his $52 million gift.
Arthur Edwin Kennelly, was an Irish-American electrical engineer.
Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thus increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
Alexander Stepanovich Popov was a Russian physicist, who was one of the first persons to invent a radio receiving device.
John Stone Stone was an American mathematician, physicist and inventor. He initially worked in telephone research, followed by influential work developing early radio technology, where he was especially known for improvements in tuning. Despite his often advanced designs, the Stone Telegraph and Telephone Company failed in 1908, and he spent the remainder of his career as an engineering consultant.
The invention of radio communication, although generally attributed to Guglielmo Marconi in the 1890s, spanned many decades, from theoretical underpinnings, through proof of the phenomenon's existence, development of technical means, to its final use in signalling.
Ronold Wyeth Percival King was an American applied physicist, known for his contributions to the theory and application of microwave antennas. He published twelve books and over three hundred articles in his area, as well as mentored one hundred doctoral dissertations.
Earle Melvin Terry was an American physicist, known for contributions to wireless transmission systems. He was born in Battle Creek, Michigan, and obtained a B.A. (1902) from the University of Michigan, as well as a Ph.D. from the University of Wisconsin–Madison (1910). He joined the faculty at the same place, where he stayed since. His fame comes from developing the WHA (AM) radio transmissions (1914), work jointly with Edward Bennett (physicist).
WINLAB is the Wireless Information Network Laboratory, a research laboratory at Rutgers University, that is dedicated to research in a number of disciplines related to wireless communications. It consists of a number of faculty members from the Computer Science and Electrical & Computer Engineering departments at Rutgers University and research scientists. It is housed on a separate facility, away from the main engineering campus of Rutgers University. The lab is famous for a pioneering early work during the development of cellular networks. It also houses the ORBIT testbed, the largest indoor wireless testbed of its kind in the world, housing more than 1200 radio nodes in a single room. The laboratory has approximately 40 PhD students, 20 MS students, and 2 Undergraduate students advised by approximately 20 full-time professors. WINLAB is funded by grants from its industry sponsors, the National Science Foundation, as well as Rutgers University and other agencies.
The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors. He claimed this system would allow for "the transmission of electric energy without wires" on a global scale as well as point-to-point wireless telecommunications and broadcasting. He made public statements citing two related methods to accomplish this from the mid-1890s on. By the end of 1900 he had convinced banker J. P. Morgan to finance construction of a wireless station based on his ideas intended to transmit messages across the Atlantic to England and to ships at sea. His decision to change the design to include wireless power transmission to better compete with Guglielmo Marconi's new radio based telegraph system was met with Morgan's refusal to fund the changes. The project was abandoned in 1906, never to become operational.
Microwave engineering pertains to the study and design of microwave circuits, components, and systems. Fundamental principles are applied to analysis, design and measurement techniques in this field. The short wavelengths involved distinguish this discipline from Electronic engineering. This is because there are different interactions with circuits, transmissions and propagation characteristics at microwave frequencies.
Lloyd Espenschied was an American electrical engineer who invented the modern coaxial cable with Herman Andrew Affel.
Richard D. Gitlin is an electrical engineer, inventor, research executive, and academic whose principal places of employment were Bell Labs and the University of South Florida (USF). He is known for his work on digital subscriber line (DSL), multi-code CDMA, and smart MIMO antenna technology all while at Bell Labs.
