Abstract

Electromagnetic crystal (EMXT) structures are used as the waveguide sidewalls of a Ka-Band waveguide cavity. With InP hetereobarrier varactors (HBV) embedded, the EMXT structure acts as an electronically tunable surface impedance in place of the normal conducting metal sidewalls. By controlling and varying the sidewall impedance with a dc voltage, the EMXT waveguide propagation constant is varied and the effective electrical length of the cavity changed. The center of the pass band was tuned from 31.6 GHz to 33.2 GHz by varying the varactor bias from 0 to 10V. It is demonstrated that the guide width can play a significant role in controlling tuning range. Good agreement between measured and simulated band-pass response was obtained.
