Basque is the last surviving Paleo-European language spoken indigenously in Europe, predating the Indo-European languages of the Bronze Age invasion of Europe from the Black Sea by pastoralists whose descendant languages dominate the continent today. Basque is spoken by the Basques and other residents of the Basque Country, a region that straddles the westernmost Pyrenees in adjacent parts of northern Spain and southwestern France. Linguistically, Basque is classified as a language isolate, as a relationship to any of the other known extinct pre-Indo-European languages of Europe has not been established, nor is it related to the later arriving Indo-European languages. The Basques are indigenous to, and primarily inhabit, the Basque Country. The Basque language is spoken by 28.4% (751,500) of Basques in all territories. Of these, 93.2% (700,300) are in the Spanish area of the Basque Country and the remaining 6.8% (51,200) are in the French portion.
In physics, a plasmon is a quantum of plasma oscillation. Just as light consists of photons, the plasma oscillation consists of plasmons. The plasmon can be considered as a quasiparticle since it arises from the quantization of plasma oscillations, just like phonons are quantizations of mechanical vibrations. Thus, plasmons are collective oscillations of the free electron gas density. For example, at optical frequencies, plasmons can couple with a photon to create another quasiparticle called a plasmon polariton.
In physics, polaritons are quasiparticles resulting from strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation. They are an expression of the common quantum phenomenon known as level repulsion, also known as the avoided crossing principle. Polaritons describe the crossing of the dispersion of light with any interacting resonance. To this extent polaritons can also be thought of as the new normal modes of a given material or structure arising from the strong coupling of the bare modes, which are the photon and the dipolar oscillation. The polariton is a bosonic quasiparticle, and should not be confused with the polaron, which is an electron plus an attached phonon cloud.
The University of the Basque Country is a Spanish public university of the Basque Autonomous Community.
Surface plasmons (SPs) are coherent delocalized electron oscillations that exist at the interface between any two materials where the real part of the dielectric function changes sign across the interface. SPs have lower energy than bulk plasmons which quantise the longitudinal electron oscillations about positive ion cores within the bulk of an electron gas.

Many Basques arrived in Chile in the 16th, 17th, 18th, 19th and early 20th century from their homeland in northern Spain and parts of southwestern France, as conquistadors, soldiers, sailors, merchants, priests and labourers. Due to their traditional hard work and entrepreneurship, many of them rose to the top of the social scale and intermarried into the Chilean elites of Castilian descent, giving birth to the new Basque-Chilean aristocracy in Chile. This union is the basis of the Chilean elite of today. But also, they immensely contributed to the ethnic make up of the bulk of the Chilean population. The Basque settlers also intermarried into the Mestizo and Castizo population of central Chile in the middle of the colonial period to form the large Criollo population that exists in Chile today; Castizos create modern middle and lower classes. Many years after the first waves of settlers, thousands of Basque refugees fleeing Spanish Civil War in 1939 also settled and have many descendants in the country and have even intermarried with Spanish ethnic groups other than Castilians, and other European ethnic groups. An estimated 1.6 million (10%) to 5 million (30%) Chileans have a surname of Basque origin. This figure is to the least as the number of Basque descendence is great and plentiful. If one were to compare the large wave of Basques that fled to the population in the Basque Country you can see that in a way ethnically speaking Chile has more Basque blood than the country of origin.
The Basque Country, also called Basque Autonomous Community, is an autonomous community in northern Spain. It includes the Basque provinces of Álava, Biscay, and Gipuzkoa. It also surrounds an enclave called Treviño, which belongs to the neighboring autonomous community of Castile and León.
Surface plasmon polaritons (SPPs) are electromagnetic waves that travel along a metal–dielectric or metal–air interface, practically in the infrared or visible-frequency. The term "surface plasmon polariton" explains that the wave involves both charge motion in the metal and electromagnetic waves in the air or dielectric ("polariton").

Miren Nekane Balluerka Lasa is a Basque psychologist and university professor.
Spoof surface plasmons, also known as spoof surface plasmon polaritons and designer surface plasmons, are surface electromagnetic waves in microwave and terahertz regimes that propagate along planar interfaces with sign-changing permittivities. Spoof surface plasmons are a type of surface plasmon polariton, which ordinarily propagate along metal and dielectric interfaces in infrared and visible frequencies. Since surface plasmon polaritons cannot exist naturally in microwave and terahertz frequencies due to dispersion properties of metals, spoof surface plasmons necessitate the use of artificially-engineered metamaterials.
