摘要
The existence of multiple reflections in TeraHertz; optical system causes numerous problems in applications ranging from astronomical to medical instrumentation. We have performed a detailed theoretical study, using waveguide and free-space modal matching, of the high-Q modes that appear on THz; optical paths. Highly accurate measurements at 0.48 THz; reproduce in detail the complex behaviour that was predicted theoretically. This work opens up the possibility of designing schemes for removing these troublesome effects.
