Properties of Infrared Cat-Whisker near 10.6 Microns.

摘要

Radiation patterns of 10.6 microns infrared antennas have been obtained experimentally and interpreted by means of a simple theory. It is found that the effective antenna is equal to the length of the etched portion of the sharpened cat-whisker antenna. This effective antenna length appears to be caused by decoupling of the electromagnetic field across a shape discontinuity of the antenna wire. The results suggest a simple means for defining the shape and size of infrared antenna structures. (Author)
