Terahertz radiation from high-order guided mode excited by a train of electron bunches
Abstract:
A new radiation scheme, which adopts the high-order harmonics of a train of electron bunches to excite the high-order guided mode, is proposed and investigated by numerical simulations. By applying this scheme, the radiation with frequency close to 1 THz is generated from a waveguide with relatively big-size structure, and the bunching frequency is much lower than the radiation frequency. This scheme may offer a promising candidate for practical terahertz source since it breaks the two main bottlenecks of the vacuum electronic devices in the terahertz region: very tiny-size structure and unapproachable electron beam.

Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore,...
