Microwave anechoic chamber material is a pyramidal shaped, carbon loaded elastic polyurethane foam EM absorber material. This material may be applied for covering of anechoic chambers, and for construction of test equipment for antenna measurements. Absorber is made in form of panel.

Applications

Broadband absorbers suitable for in-door measurements.Below 100mm thickness, used for small shielding roomAbove 100mm thickness, used for huge shielding room or dark roomIt is available in other sizes and customer specified configurations upon requestUsed in making microwave anechoic chambers for performing measurements like RCS,antenna Measurements etc.

Using polyurethane foam as matrix materials and with warter-proof coating on the surface ,the absorption element is carbon, dust-free drop;usually the color of product surface is light blue ,of course ,the surface color could be changed as customization. Product meets the testing standard of NRL8093 (US),all raw materials of comply with RoHS,by using flame retardant material, no volatilization,no abnormal odour, non-toxicity;materials is stable after a long-term use .

Standard packing

SEMG offers a diverse product line that includes microwave absorbing elastomers, phasecancellation materials, microwave absorbing foam, specialty microwave absorbers, custom magnetic absorbers and advanced frequency selective products. All of our absorbers can be used at higher frequencies than traditional shielding and with other EMI shields to extend frequency range. SN-MA series and other sheet form elastomeric absorbers can be installed easily with pressure sensitive adhesive, often directly onto high-frequency board-level components to absorb unwanted radiated and surface wave EMI, and meet FCC requirements without shielding. P.S. Microwave absorbers are used to solve a wide variety of problems such as internal cavity resonances, antenna pattern shaping, and high-frequency interference.
