| Summary: | "The new book on antenna analysis and synthesis takes an unusual approach and relies heavily on the long line theory. The application of this theory to the analysis of processes in antennas is not new, but is usually used only as an auxiliary method. It is considered insufficiently rigorous compared to the method of integral equations, therefore, when analyzing processes in known and proposed antennas, as well as fields in the surrounding space. The specialists prefer to rely on numerical results obtained by solving integral equations. Lovers, as a rule, are limited to simple equivalent circuits, consisting of lumped elements included in the resonant circuit (capacitor, inductor, resistor). The method based on the use of elementary dipoles with a current constant along the length, as noted by King, bypasses the main issues of antenna problems and does not solve them. The application of the theory of long lines, the dimensions of which are many times greater than the wavelength and are comparable to the distance to the infinitely remote surface of zero potential, corresponds to the physical content of antenna problems. In this case, the mathematical apparatus is greatly simplified. For example, despite long attempts, it was not possible to apply the method of integral equations to a circular loop antenna with dimensions exceeding the wavelength. The theory of long lines makes it possible to solve such problems"-- |
