PLANAR TRANSMISSION-LINE PERMITTIVITY SENSOR AND CALIBRATION METHOD FOR THE CHARACTERIZATION OF LIQUIDS, POWDERS AND SEMISOLID MATERIALS

摘要

A low cost planar transmission line sensor and simple calibration method for measuring the complex permittivity of materials with minimal sample preparation over a wide band of radio- and microwave frequencies. The sensor is also used for measuring anisotropic dielectric properties of materials with a defined grain.
