| Abstract: | The generation and detection of guided wave terahertz (THz) transients in microstrip transmission line systems is demonstrated
at both room and cryogenic (∼ 4 K) temperatures using thin film low-temperature-grown GaAs (LT-GaAs) switches, excited by
a 100 fs, 80 MHz repetition rate pulsed Ti:Sapphire laser. The characterisation of passive filter elements formed in the microstrip
line is reported, together with their response to the application of dielectric loads of varying thickness at room temperature. |
