Carbon-Based Microwave Absorbers

Cuming Microwave manufactures a family of flexible carbon loaded microwave and radar absorber materials. These are all electrically resistive materials which attenuate RF energy through ohmic loss. These Carbon based microwave absorbers such as C-RAM MT have high dielectric loss over a very broad frequency range, but are available in a range of loadings and thicknesses to be optimized for particular frequencies. Many grades are available with a peel-and-stick adhesive for ease of application.
Some of the materials, such as C-RAM LF and AR, have impedance gradients and are designed to absorb free-space planar waves. They are often used to cover metal structures in the path of RF energy to eliminate unwanted reflections. These materials can be weather-wrapped for outdoor applications.
Cuming Microwave also offers carbon loaded microwave absorbers such as C-RAM LF and AR, This type of microwave absorber has an impedance gradient and are designed to absorb free-space planar waves. They are often used to cover metal structures in the path of RF energy eliminating unwanted reflections. Carbon loaded microwave absorbers can be weather-wrapped or sprayed with a protective coating for outdoor applications.
Cuming Microwave application engineers can help you with your RF energy management problems, and help specify a product to quickly solve your problem. Carbon loaded microwave absorber grades are available with a peel-and-stick adhesive for ease of application. Carbon loaded microwave absorbers can also be ordered diecut or waterjet to your drawing.
