The scattered far field from a halfwave dipole illuminating a perfectly conducting quarterplane is calculated. The calculation is based on a calculation of the radial electric and magnetic field...
The spectrum of creeping waves that can exist on the surface of a dielectric coated cylinder is determined by the poles in the Green's function for the cylinder. Accounts of the position of these...
Modern communications satellites are equipped with high gain reflector antennas with contoured beams for various purposes. A contoured beam of complex cross section is generated by exciting...
The paper presents various methods for the calculation of the field reflected from a subreflector in a dual reflector antenna system. It is demonstrated that the physical-optics (PO) solution...
Two transformations for accelerating the convergence of infinite M-dimensional series are presented. They are generalizations of Shanks' e- transformation and Levin's one-dimensional...
A waveguide polarizer with resonant notches in a septum is investigated. The Wiener-Hopf technique is employed to derive theoretical design data and the results are compared to experiments for a...
The caustics for the singly diffracted rays from a circular disk are investigated when the rays emanate from a source which is placed off the axis of the disk. Either two or four singly diffracted...
The near-field and the far-field patterns from the high-gain S band antenna on the METEOSAT are calculated by the geometrical theory of diffraction. The far field is transformed into the near...
A theoretical formulation, in terms of combined magnetic and electric field integral equations, is presented for the class of electromagnetic problems in which one or more wire antennas are...
