Novel Microwave Technique for Industrial Measurements

Abstract

Based on traditional microwave techniques a new branch is rapidly growing: The application of microwaves for industrial measurements and process control. In many cases microwaves are superior to other methods because of the specific microwave behaviour of materials and the possibility of contact-free, remote probing.The use of microwave techniques has been stimulated by the development of integration techniques both for the microwave part and the signal processing part which allows the construction of compact instruments. This paper includes a general report on the various applications of microwaves in industrial measurement and a discussion of the technical aspects. Some applications of this technique in medical diagnostic will also be mentioned.
