Microwave Absorber Products

Low Loss Dielectric Stock Materials- 210 Series

Cuming Microwave manufactures a full line of low loss dielectric materials. Our materials range in dielectric constant from 1.05 to 25. These materials have unique dielectric and physical properties. Dielectric materials can be used to adjust the Q of cavities, as impedance transitions, substrates for stripline antennas, in transmission lines, smart skins, as dielectric radomes, dielectric spacers, or for circuit substrates.

Products are available in rod or sheet form, pack-in-place syntactic foam, rigid foam sheet stock, or as a two-component foaming system. In addition to standard configurations, we can custom fabricate components and work with our customers to find creative solutions to tough problems.
