Title Of Article :
Microwave System for the Dielectric Analysis and Moisture Evaluation
Abstract :
A detailed method for determining the moisture level and the dielectric properties of materials using microwave free-space transmission/reflection measurements system and the modular HEPHAISTOS-System (High Electromagnetic Power Heating Automated Injected STructures Oven System) is presented. Steps involved in the determination process are explained and their effect on the S-parameters is presented. A through-reflect-line/match (TRL/M) free-space calibration method was used, which greatly reduces system errors owing to its simple and stationary nature.
