Abstract

Abstract

The measurement of reflection from an open-ended coaxial line is a simple and nondestructive technique of determining the dielectric property of materials. The electromagnetic field in the vicinity of the aperture is studied by means of rigorous field matching method. The reflection coefficient is computed by moment method as a function of the dielectric constant. The validity of the theoretical results is ested by comparing the numerical evaluation with previous paper. Furthermore, a method fo data inversion is provided.
