Abstract :
According to an air gap variation in a parallel-plate waveguide (PPWG), a tunable terahertz (THz) single resonance with a transverse-electromagnetic (TEM) mode can be demonstrated. When the air gap between the metal plates of the PPWG is controlled from 60 to 240 μm using a piezo-actuator, the resonant frequency is changed from 1.75 up to 0.62 THz, respectively. We also demonstrate the tunable THz single resonance by using a piezo-actuator and a finite difference time-domain (FDTD) simulation.
