Research Abstract

The propagation properties of leaky millimeter waves in the semiconductor H-guide containing optically induced plasma layer have been investigated by utilizing the numerical calculation based on the exact guidedwave theory. The mechanism of high-speed transition from guided modes to leaky waves has been shown with the numerical example of dispersion curves. First we derived the solution to the complex eigenvalue equation by Muller method, and then obtained the complex propagation constant and wave numbers for each direction. With the calculated power flow vectors, the property of leaky waves was revealed graphically. From the figures of the vector form of leaky waves, we found that the direction of average power density drastically changed with the plasma density due to illuminating intensity and also with the operating frequency. In this research we obtained the basic data for designing the leaky wave antenna using a silicon H-guide in the range between 26.5 and 40GHz. We also calculated the propagation characteristics for GaAs as a semiconductor inserted into the H-guide, which was expected to be fast response, and for higher frequency range such as 60GHz that was promising for a practical use. As an experimental trial, we measured the leaky wave radiating from the horn of H-guide, and examined the directivity characteristics due to the illuminating intensity.Some differences between the measurement and the theoretical results have been left at this stage, and their improvement for the experimental conditions are the following assignment.
