Paper Abstract

The energy-decay behavior of pulsed microwaves launched in air has been investigated with different microwave optics geometries. Experimental results, related to different geometries indicate that within the range of our measurements, the detected power referred to the peak intensity of pulsed microwave, decays much slower than those counterparts predicted by the Friis transmission equation as well as by the radar equation. In addition, a novel standing wave measuring technique is presented, where the concept of the `apparent wavelength' is experimentally demonstrated. These observed phenomena may give rise to potential applications in bioengineering, communications and control, where maintenance of the initial pulse amplitude and/or energy profile over long distances is important.
