Comparison of dielectric properties using metal-backed and transmission reflection method / Jane Jaong

This paper presents free-space measurements on metal-backed samples and planar samples such as teflon, polyvinyl-chloride (PVC), polypropylene (PP), polyethylene (PE) and nylon in free-space. This free-space measurement is conducted m an anechoic chamber and operated in the frequency range of 8.0-12...
