Radiation Conductance and Pattern of Array Antenna on a Non-Confocal Dielectric-Coated Elliptic Cylinder
The formulation for the radiation pattern and conductance of axial slots array antenna on a dielectriccoated elliptic cylinder is presented. The coating is assumed to be non-confocal. The analytical solution, given here, is based on the eigen function technique and the addition theorem of Mathieu functions. The excited apertures are assumed to generate a TM polarized wave. Accordingly, the obta...
متن کاملWake-field generated by a line charge moving in the vicinity of a dielectric cylinder
The wake-field generated by a moving line charge in the vicinity of a dielectric cylinder is analyzed. It is shown that the emitted energy increases logarithmically with the kinetic energy ðg 1Þ of the line charge and decays exponentially as a function of the ratio h=R; where R is the cylinder radius and h is the distance of the line charge from the cylinder’s axis. Upon investigation of the an...
متن کاملSynchrotron radiation from a charge moving along a helix around a dielectric cylinder
In this paper we investigate the radiation emitted by a charged particle moving along a helical orbit around a dielectric cylinder immersed into a homogeneous medium. Formulae are derived for the electromagnetic potentials, electric and magnetic fields, and for the spectralangular distribution of the radiation in the exterior medium. It is shown that under the Cherenkov condition for dielectric...
متن کاملScattering by a Perfect Electromagnetic Conducting Elliptic Cylinder
An exact analytic solution is presented to the problem of scattering of a plane wave from a perfect electromagnetic conducting (PEMC) elliptic cylinder, using the method of separation of variables. The formulation is carried out by expanding the incident as well as the scattered electromagnetic fields in terms of appropriate angular and radial Mathieu functions and a set of expansion coefficien...
متن کاملCasimir Energy for a Dielectric Cylinder
In this paper we calculate the Casimir energy for a dielectric-diamagnetic cylinder with the speed of light differing on the inside and outside. Although the result is in general divergent, special cases are meaningful. The well-known results for a uniform speed of light are reproduced. The self-stress on a purely dielectric cylinder is shown to vanish through second order in the deviation of t...
