Abstract/OtherAbstract:
|
Transmission and dispersion relation of THz waves in two-dimensional photonic crystal (PC) composed of metal rods are studied by using finite-difference time-domain simulation and THz time-domain spectroscopy measurement. The PC is embedded in a parallel metal plate waveguide with an air gap between the PC and one of the plates. The photonic-band-gap well-defined at small air gap narrows systematically with opening the air gap and disappears when the air gap is 2 ∼ 3 times the rod height, where the two-dimensional nature of PC is destroyed. The mechanical tunability of photonic band structure would be useful in functional THz device. |
