Microwave Permittivity

Methods for measuring the microwave permittivity and permeability of materials are considered. The specific features and applicability conditions of measurement methods in transmission lines and in free space are shown, and the measurement errors are analyzed along with the calibration procedures applied for reducing the errors. Individual sections of the articles contain descriptions of scalar, resonance, quasistatic, and quasioptic methods. It has been determined that out of many existing techniques, the NicolsonRossWeir measurement method in a coaxial line and also the method for measuring the permeability of thin ferromagnetic films with the use of a shortcircuited strip cell are most widely applied. By using these methods, the majority of matters concerned with studying the microwave properties of materials can be solved.

Fluid Flow Modeling

Accurate measurement of Permeability is critical for fluid flow modeling in porous media. Various experimental methods have been devised that measure permeability as a porous material property. These experiments are based most commonly on Darcy’s law. Liquid flow and gas flow methods of permeability measurement for in-plane and transverse directions are detailed. Issues related to these methods are discussed. Some associated permeability models are discussed. Alternative methods of permeability determination based on cross transport phenomenon are presented.
