Absorbers

Pyramidal Microwave Absorbers

JVMFU absorber product line is a complete range of high Performance Pyramidal Microwave Absorbers available in wide range of thickness and absorbencies. Variety of thickness gives the chamber designer the opportunity to choose grades appropriate for specific frequencies and incidence angles by using low density, flexible foam, impregnated with a carbon formulation to achieve the desired electrical performance. The pyramidal structure gives it the geometrical matching and the carbon dispersed gives the attenuation required. Provides Engineers with the building blocks needed in the design and construction of RF absorbing surface used in Anechoic Chambers, Antenna Assemblies and Microwave Measuring facilities.
