Abstract

This paper introduces an innovative method for measuring the complex permittivity of dielectric materials using samples of arbitrary shape and size. Conventional techniques for dielectric measurement typically require either large, flat samples or materials in powdered form, which can be restrictive for modern applications or the study of archaeological artifacts. Our approach leverages Resonant Cavity Perturbation (RCP) theory, enabling the measurement of small, irregularly shaped samples by analyzing perturbations from three orthogonal modes within a cuboid cavity. The technique is validated through measurements of various materials, including polymers and woods, demonstrating its ability to provide accurate dielectric data at microwave frequencies. This method holds significant potential for non-destructive characterization, particularly in the analysis of archaeological objects and the evaluation of new materials.
