Diffraction

--> Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit.

Electrical conductor

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions.

Electromagnetic spectrum

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.

Electron

The electron is a subatomic particle, symbol or, whose electric charge is negative one elementary charge.

Evanescent field

In electromagnetics, an evanescent field, or evanescent wave, is an oscillating electric and/or magnetic field that does not propagate as an electromagnetic wave but whose energy is spatially concentrated in the vicinity of the source (oscillating charges and currents).

Hans Bethe

Hans Albrecht Bethe (July 2, 1906 – March 6, 2005) was a German-American nuclear physicist who made important contributions to astrophysics, quantum electrodynamics and solid-state physics, and won the 1967 Nobel Prize in Physics for his work on the theory of stellar nucleosynthesis.

Insulator (electricity)

An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

Isotropy

Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way").

Light

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.

Metamaterial

A metamaterial (from the Greek word μετά meta, meaning "beyond") is a material engineered to have a property that is not found in nature.

Near and far field

The near field and far field are regions of the electromagnetic field (EM) around an object, such as a transmitting antenna, or the result of radiation scattering off an object.

Perfect conductor

A perfect conductor or perfect electric conductor (PEC) is an idealized material exhibiting infinite electrical conductivity or, equivalently, zero resistivity (cf. perfect dielectric).

Plasmon

In physics, a plasmon is a quantum of plasma oscillation.

Relative permittivity

The relative permittivity of a material is its (absolute) permittivity expressed as a ratio relative to the permittivity of vacuum.

New!!: Extraordinary optical transmission and Relative permittivity · See more »

Surface plasmon

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 (e.g. a metal-dielectric interface, such as a metal sheet in air).

New!!: Extraordinary optical transmission and Surface plasmon · See more »

Surface plasmon resonance

Surface plasmon resonance (SPR) is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light.

Wave interference

In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude.

New!!: Extraordinary optical transmission and Wave interference · See more »

Wavelength

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
