The multiplicative receiving array uses two arrays. The first is a conventional array with elements uniformly spaced at # /spl equiv/ /spl lambda//2. Immediately beside it, the second thinned array has elements with spacing of one half the total size

Thin-wire transmission lines and dipoles, whose diameters are much less than the operating wavelength, carry currents which are essentially sinusoidal in form. Moreover, the electromagnetic field radiated by the filamentary (a to infinity ) straight

The authors consider a center-fed solid circular cylindrical dipole radiating in a circular waveguide terminated in infinite ground planes. Numerical results show how the input admittance depends on the dipole length, feed gap width, and waveguide ra

The author consider a strip dipole with an assumed current density on its surface and uses the Poynting vector method to determine the complex power leaving the surface. This makes it possible to obtain the input impedance at the dipole's infinitesim

In the classic Poynting vector method for determining the impedance of a thin dipole, the current density on the surface of the circular cylindrical conductors of radius a /spl Lt//spl lambda/ is assumed to be a sinusoidal standing wave, vanishing at

This paper extends the classical problem of electromagnetic scattering of spherical conductors to the case of two coalescing spheres of different size. The incident field is a linearly polarized plane wave with arbitrary polarization angle /spl gamma

The scattered field is represented by a series of outgoing Hankel-type cylindrical waves. These waves are transformed into a set of plane waves at each of the four walls of the perfectly conducting cylinder, where field matching [(E/spl I.oarr//sub i
