Millimeter and Submillimeter Waves and Frequency Selective Surfaces

摘要

We have investigated two different class of problems in this effort. The first of these falls in the category of microwave and millimeter wave integrated circuits and the second is concerned with frequency selective surfaces, or FSS. Our research in the millimeter wave area has focused on the development of analytical and numerical techniques for determining the characteristics of planar transmission lines, as well as circuit components and antennas that are compatible with these lines. As for frequency selective surfaces, our investigation of the FSS screens dealt with the development of methodologies for predicting the transmission and reflection properties of these screens as a function of the frequency. Both the free-standing screens and those with a dielectric substrate or superstate have been studied. In addition, curved and finite screens have also been investigated.
