Profile: HVS Technologies, Inc. designs and develops free space systems for microwave and mm-wave characterization of electromagnetic properties of materials. We also provide free space systems for antenna radiation pattern measurement systems, high power microwave processing systems, microwave fixtures, and software for these systems. We offer solutions for high and low temperature characterization of electromagnetic properties of materials. Our free space measurement system measures electromagnetic properties, dielectric permittivity, magnetic permeability, radar absorption, chirality parameter, surface resistivity and shielding effectiveness. Our automated free space measurement system consists of nine servo controlled degrees of freedom, two linear and two rotary axes for each spot focused horn antenna & one linear positioner for the sample holder.
