Reflection/transmission measurement system for planar materials and verification by thin wire grids

Abstract

This paper describes a measurement system to evaluate the reflection and transmission (R/T) properties of planar materials have been constructed within the Open-Range EM Laboratory (ASEMLAB) of Gebze Institute of Technology. This manuscript describes this measurement system, calibration process, and the results of an application - measurement of the R/T coefficients of a thin wire mesh. In order to check the measured R/T coefficients of the thin wire mesh a periodic method of moments (PMM) code has been developed. The currents that leave one periodic cell and enter the next are handled in a novel way. © 2011 IEEE. © 2011 Elsevier B.V., All rights reserved.
