Injection resin Absorber for Millimeter wave

We newly have developed Injection resin Absorber for Millimeter wave, which highly absorbs wide range RF from 77-80GHz.
It is applicable for radar horn of mmW Short Range Radar, and for interference noise absorption between TX-RX elements in a mmW radar ECU unit.
We could supply injection absorber of such resin as PA, PP, PC and Elastomer.
It consists of single layer so that make it lighter and more cost effective.
