Abstract :
The author considers an extremely general technique which allows the most general nonuniform, lossy, and anisotropic linear media to be treated in electromagnetic problems by developing the weighted residual method for non-Hermitian behavior. Interfacial boundary conditions are partly left to the volumetric integrals, some to the surface integrals, and some as constraints imposed directly on the fields. Conversion of some of the volume integrals to surface integrals is done applying integration by parts in a more explicit and direct fashion than that employed for simpler media where various Green´s theorems are used.<>
