Microwave Materials

It may be surprising to many that absorbers of electromagnetic radiation were conceived and investigated as far back as the mid 1930's.  The earliest record involved a simple resonant absorber that was designed for application to the back of a 2 GHz antenna in order to improve its front-to-back ratio.  Today, some 80 years later, engineers working at VHF, UHF, microwave, and millimeter wave frequencies have access to a wide variety of materials to not only absorb RF energy but also control it with low loss dielectrics and highly conductive shielding materials.  Below is a product listing and description of the brand names offered by Laird.
