Roger Fuller Harrington (born December 24, 1925) is an American electrical engineer and professor emeritus at Syracuse University. [1] He is best known for his contributions to computational electromagnetics with his development of method of moments (MoM). [2] Harrington's 1968 book, Field Computation by Moment Methods, is regarded as a pivotal textbook on the subject. [3] [4]
Harrington was born on December 24, 1925, in Buffalo, New York. He started majoring in electrical engineering in 1943 at Syracuse University; his studies were interrupted in the following year by World War II. During this time, he served as an instructor under the Electronics Training Program at the U.S. Naval Radio Materiel School in Dearborn, Michigan, while working as an electronics technician. He completed his studies after the war, receiving B.S. and M.S. degrees in 1948 and 1950, respectively. Briefly remaining at Syracuse University as a research assistant and instructor, he started his doctoral studies under Victor H. Rumsey at Ohio State University, receiving his PhD in 1952. [2]
Harrington returned to Syracuse University following his doctoral studies, working there as a professor until his retirement in 1994. Following his retirement, he briefly worked as a visiting professor at University of Arizona. During his tenure at Syracuse University, he has worked on research projects for the U.S. Army Signal Corps, Office of Naval Research, General Electric and the U.S. Air Force Office of Scientific Research. [4] He has also held visiting professorship positions at University of Illinois in between 1959 and 1960, University of California, Berkeley in 1964 and the Technical University of Denmark in 1969. [2]
Harrington is a recipient of IEEE Centennial Medal, IEEE Antennas and Propagation Society Distinguished Achievement Award and IEEE Electromagnetics Award in 1984, 1989 and 2000, respectively. [2] In 2014, he was awarded the Benjamin Franklin Medal in electrical engineering for his contributions to the study of electromagnetics. [4] He currently resides in Wheaton, Illinois with his daughter. [2]
Harrington has published two standard engineering textbooks, Introduction to Electromagnetic Engineering in 1958 and Time-Harmonic Electromagnetic Fields in 1961. In 1968, he published Field Computation by Moment Methods, which introduced the unified and generalized theory of method of moments (MoM), an integral equation method for solving electromagnetic problems. [5] [6] [2] The development of the method stemmed from Harrington's initial interest in using electromagnetic fields in thermonuclear fusion research. [4] Harrington further developed the method in his future publications; method of moments later became one of go-to methods in the study of antennas, integrated circuits and waveguides, among others. Harrington's further work included the study of radiation and scattering in bodies of revolution, dielectric scattering, field integral equations and theory of characteristic modes. [2]
Harrington also expanded Lan Jen Chu and Harold Alden Wheeler's theory on the fundamental limits of electrically small radio antennas; [7] [8] Chu–Harrington limit, which yields a lower bound for the Q factor of a small radio antenna, is named after him.
Finite-difference time-domain (FDTD) or Yee's method is a numerical analysis technique used for modeling computational electrodynamics. Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear material properties in a natural way.
Computational electromagnetics (CEM), computational electrodynamics or electromagnetic modeling is the process of modeling the interaction of electromagnetic fields with physical objects and the environment using computers.
Constantine A. Balanis is a Greek-born American scientist, educator, author, and Regents Professor at Arizona State University. Born in Trikala, Greece on October 29, 1938. He is best known for his books in the fields of engineering electromagnetics and antenna theory. He emigrated to the United States in 1955, where he studied electrical engineering. He received United States citizenship in 1960.
Characteristic modes (CM) form a set of functions which, under specific boundary conditions, diagonalizes operator relating field and induced sources. Under certain conditions, the set of the CM is unique and complete (at least theoretically) and thereby capable of describing the behavior of a studied object in full.

In electromagnetism, surface equivalence principle or surface equivalence theorem relates an arbitrary current distribution within an imaginary closed surface with an equivalent source on the surface. It is also known as field equivalence principle, Huygens' equivalence principle or simply as the equivalence principle. Being a more rigorous reformulation of the Huygens–Fresnel principle, it is often used to simplify the analysis of radiating structures such as antennas.

The method of moments (MoM), also known as the moment method and method of weighted residuals, is a numerical method in computational electromagnetics. It is used in computer programs that simulate the interaction of electromagnetic fields such as radio waves with matter, for example antenna simulation programs like NEC that calculate the radiation pattern of an antenna. Generally being a frequency-domain method, it involves the projection of an integral equation into a system of linear equations by the application of appropriate boundary conditions. This is done by using discrete meshes as in finite difference and finite element methods, often for the surface. The solutions are represented with the linear combination of pre-defined basis functions; generally, the coefficients of these basis functions are the sought unknowns. Green's functions and Galerkin method play a central role in the method of moments.
