Stripline Resonator for Electromagnetic Measurements of Materials

摘要

A stripline resonator was used to measure the relative dielectric and magneticproperties of materials in the frequency range from 150 MHz to 2 GHz. Measurement accuracy relates strongly to the dimensions of the resonator. Consequently, equations used in the design of a resonator and the resonator design are described and design tradeoffs are discussed. Dielectric and magnetic measurements are included to support the design of our resonator. Discussions of important concepts used in measurement correction, such as sample shape and size and demagnetization, are provided.
