Abstract
The classical Fresnel zone criterion is used to examine microwave propagation through an open ended cylindrical metallic tube. It is shown that there exists a near free-space propagation region between the transmit antenna and the receive antenna. This principle is used to develop a microwave absorption spectrometer. Experimental results are presented to validate the concept.
