Interface conventions will allow users to add their own solvers to the product's front-end.

The aim is reached by a combination of two rigorous techniques, namely eigenfunction expansions (EE) and volume integral equations (IE). The solution leads to a system of linear algebraic equations, whose unknowns represent the field values over the inclusion cross-section. The developed model can be efficiently utilized to solve the electromagnetic compatibility problems, to construct composite materials with predetermined electromagnetic properties and, especially, when investigating the electromagnetic fields influence on biological structures. In the last case, the cylinder is a good model of a bath with matching liquid, where the investigated object is immersed, or a model of some biological structures such as arm, leg, etc.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.

The elementary electric or magnetic dipoles are usually assumed as emitters. In each of these cases the Hertz potentials are introduced, which satisfy partial differential equations with separable variables. Solutions to this equations are sought either in the form of a series in terms of eigenfunctions of the angular operator or in the form of a series in terms of eigenfunctions of the radial operator. The transition from one series to the other is accomplished through the Watson transformation. Attempts to generalize this scheme to the case of more sophisticated waveguide and emitter models led the author to the conclusion that the scheme should be modified. To elucidate the essence of the problem, a very simple model is considered. Unlike the classical scheme, we abandoned the idea of introducing any potentials, and formulated boundary-value problems for the components of fields. The objective of this paper is to devise a reasonably rigorous mathematical scheme for seeking the formal expressions for solving a system of Maxwell's equations.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.
