Cavities are an indispensable tool in the material characterization toolbox. Particularly useful in the characterization of low loss dielectric materials, cavity methods work best when the cavity shape and corresponding modes are tailored for the class of materials to be studied. Whether rectangular, cylindrical, parallel plate, or other specialty configuration, DSC can design and fabricate a cavity that works for your frequencies, modes of interest, and Q. Material property inversion software is also available.
