Electromagnetic Materials and their Measurement: RAM, Radome, and RAS

Course Description

This three day course introduces the physical concepts that govern electromagnetic materials, composites, and metamaterials. This physics is then applied in lectures and hands-on laboratory demonstrations to introduce students to a variety of concepts, including: material measurement principles and techniques, measurement equipment and software, and procedures necessary to generate application-oriented material property databases. The three days are split approximately 50:50 between lecture and laboratory.
