Generalized eigenfunction method for the case of dielectrically loaded antennas

The generalized eigenfunction method applied earlier to diffraction problems and in laser theory can be useful in antenna design. It can help to find within the reasonably limited amount of calculation not only static but dynamic characteristics of the antenna. The importance of the dynamic analysis is discussed, demonstrating big changes in antenna parameters in the case of transmission ( or reception) of short pulses. For high bit rate communication systems the detailed analysis of such changes is of vital importance.
