Electromagnetism of Left-handed Material

Doppler effect; Doppler effect

Modification of the frequency of a wave emitted by a source as it moves.

Hartman effect; Hartman effect

Propagation of a particle through a tunnel barrier. Its "apparent" speed seems to exceed the speed of light in a vacuum. In reality, this is a consequence of quantum mechanics.

Goos-Hänchen effect; Goos-Hänchen shift

Offset of a wave on reflection from a material surface in which it cannot propagate.

Cherenkov effect; Cerenkov effect

Offset of wavefronts produced by an object moving at a speed greater than the speed of light in a medium.

Tunneling effect

The transfer of energy across a physical barrier that normally prevents it from passing through. This is known as a tunnel barrier. In electromagnetism, this transfer often takes the form of an evanescent wave crossing the tunnel barrier. This effect is...
