Material Sensing & Instrumentation
Microwave cavity characterization complements TDR Dielectric Spectroscopy in low-loss materials, providing high-resolution permittivity and loss data at specific single frequencies. Since measurements do not change significantly with frequency in low-loss materials (Kramer-Kronig relation) cavity measurement at select frequencies provides a full characterization across the RF/microwave range.
