Abstract:

The main purpose of the present contract has been to apply the compensation theorem method to problems concerning the skywave radiation from antennas placed in areas with varying electrical properties, as for example mixed land- and sea areas. During the cause of this work first the compensation theorem method was examined and compared with other theoretical methods, and next this method was applied to the problems of sky-wave radiation from antennas placed near a straight line boundary between different media, and both the two media and the three media case were considered. Further a direct electronic computer treatment of the case of arbitrary boundaries has been discussed and modified form of the well known Fresnel zone concept has been introduced. Finally some related work not carried out under the contract is discussed. It includes some non-flat terrain problems treated by means of the compensation theorem, and a mathematical investigation of an antenna placed very close to the boundary. Author
