Radiation from an axial electric dipole with prolate spheroidal metamaterial cloak cover
Exact analytical expressions for the electromagnetic field due to a dipole source located inside and along the axis of symmetry of a prolate spheroid are provided.
Radiation From a Line Source Shielded by a Confocal Elliptic Layer of DNG Metamaterial
The two-dimensional problem of electromagnetic radiation from a line source located inside an elliptic-cylinder confocal sheath of double-negative metamaterial is solved exactly by separation of variables. Numerical results are presented and discussed for the radiation pattern and the field inside the sheath, as functions of frequency, location of the line source, and sheath thickness and eccentricity.
Algorithm 861: Fortran 90 subroutines for computing the expansion coefficients of Mathieu functions using Blanch's algorithm
A translation to Fortran 90 of Gertrude Blanch's algorithm for computing the expansion coefficients of the series that represent Mathieu functions is presented. Its advantages are portability, higher precision, practicality of use, and extended documentation. In addition, numerical validations and comparisons with other existing methods are presented.
