Implementation of Microwave Active Nulling
Abstract
We have fabricated a universal test equipment capable of measuring the phase and amplitude of the reflection wave from a coax-cable cavity resonator. Frequency-agile materials, such as ferroelectric and ferrite samples were included with the resonator so that the resonant frequency of the resonator can be tuned by applying either a bias electric voltage or a bias magnetic field Sensitive electric and magnetic tuning have been obtained, and the measurement results compared nicely with calculations. In order to enhance the sensitivity of electronic tuning resonance mechanisms have been incorporated with the reflector performance such as the structural resonance and the ferrimagnetic resonance.
