The characteristic equations giving the allowed modes of propagation of electromagnetic waves in a coaxial cable are obtained, assuming a lossless structure with the bounding sur-faces offering a reactive impedance. Only ...
Surface acoustic wave devices have been used in
various consumer products like color television, video cassette recorder, mobile telephone for cars eta. The most significant success has been in the realization of SAW ...
W'aveguides partially filled with dielectric have been studied but only the simple composite structures have been analysed exactly. The problem may be solved by considering the fields in the wave-guide inserting the various ...
