Microwave nondestructive testing of coatings and paints / Kamal Faizin Che Kasim

Microwave non-destructive testing is used as a technique of testing of coatings and paints on brass metal and glass. The method used here is free space method operating in the farfield region employing spot-focusing horn lens antennas. The measurement technique is contactless and measures the magnitude and phase reflection coefficient of dielectric materials in the frequency range of 8.0 - 12.5 GHz. In this project the objective is to analyze and measure a microwave nondestructive characteristics of coatings and paints on materials such as brass metal and glass. The obvious advantage of this technique is that the sample is not damaged during the process of measurement.
