The prolate spheroidal radial functions of the second kind have recently been computed with a full precision accuracy, in particular, for thin prolate spheroids with the use of the rapidly convergent expansion near the singular point 1 'A . By utiliz

The Infeld function expressed in terms of the outgoing prolate spheroidal radial wave function and its derivative, and employed in the expression of the input self-admittance of prolate spheroidal antennas, has accurately been calculated by using a n

The series expansion of the prolate radial functions of the second kind, expressed in terms of the spherical Neumann functions, converges very slowly when the spheroid’s surface coordinate ξ \xi approaches 1 (thin spheroids). In this paper an anal

The perturbation method of Pointcaré and Lindstedt has been used to find the asymptotic expression of a massless particle under the Reissner–Nordström metric. From this analytical expression, the deflection angle of a massless particle is express

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

In previous work of the authors (see IEEE APS-S Symp. Digest, vol.4, p.1839, 1990), a full-wave analysis was chosen to solve the problem of waveguides terminated in a perfectly conducting ground plane. However, if the ground plane is assumed to be lo

The problem of analyzing waveguides terminated in an infinite plane conductor is formulated without using Green's functions. The formulation is applicable for a source inside a waveguide as well as for an external source (e.g., a plane wave). Two pri

The authors present a full-wave modal solution to the problem of a monopole antenna fed through a ground plane by a coaxial line. The approach used is the conservation of complex power technique (CCPT). The problem is formulated, and the numerical re

The cut-off wavenumbers of elliptic sectoral resonators are analysed and their relations to the complete elliptic resonator and the sectoral circular resonator are demonstrated. From these relations approximate methods are developed for computing the
