A new technique for numerical electromagnetics

A new method for numerically solving electromagnetic boundary value problems has been independently developed by at least five groups worldwide [l-61. The unique feature of the technique is that the unknowns are analytic solutions of the field equations corresponding to sources that are some distance away from the surface where a boundary condition is being enforced. A generic name for the technique has not yet been generally accepted. Proposed names include "Extended Source Technique," "Generalized Source Technique," and "Generalized Multipole Technique," with the latter being favored by most of the workers using the method. It is hoped that a special session can be arranged for this technique at the next AP meeting in San Jose, and anyone working on this type of solution is invited to submit a paper to the AP session.
