Terahertz wave transmission within metal-clad antiresonant reflecting hollow waveguides
Abstract:
We present the transmission characteristics of THz waves in metal-clad antiresonant reflecting hollow waveguides. We have derived the equation for the blueshift of the resonance frequency. The effects of the waveguide structure on the blueshift of the resonance frequency are studied comprehensively. In particular, we find that the blueshift of the resonance frequency is strongly affected by the interval between two dielectric slabs. By changing the interval, we find that the maximum frequency-tuning range is up to 2030 GHz and the maximum sensitivity of the resonance frequency shift is up to 6950 GHz/mm at the resonance order of m=1. When the THz wave is at the near-zero loss frequency, both the loss and the dispersion of the guide modes are very low.
