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.
New!!: Extraordinary optical transmission and Insulator (electricity) · See more »
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.
New!!: Extraordinary optical transmission and Metamaterial · See more »
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.
New!!: Extraordinary optical transmission and Near and far field · See more »
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).
New!!: Extraordinary optical transmission and Perfect conductor · See more »
Plasmon
In physics, a plasmon is a quantum of plasma oscillation.
New!!: Extraordinary optical transmission and Plasmon · See more »
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.
New!!: Extraordinary optical transmission and Surface plasmon resonance · See more »
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.
