Magnetic and Electric Fields Produced from a Slow Wave circuit
A Slow wave circuit is a circuit configuration that is designed to reduce the phase velocity of a Radio-Frequency (RF) signal along a transmission line. Slow wave circuits are used in microwave engineering systems. The slow wave circuit measures 5.75” x 2” and is created from a sinusoidal copper wire placed on top of a Teflon dielectric that separates the circuit from a ground plane. A frequency of from 800-1000 MHz is applied to the circuit, and the RF magnetic and electric fields are measured using a spectrum analyzer with specialized probes, as well as an oscilloscope to measure phase variance using multiple probes. The RF field data from both measurement devices will be presented and compared to the results from the RF simulation COMSOL.
