Abstract :
New volume and volume-surface integral equations are presented for modeling inhomogeneous dielectric regions. In particular, it is shown that materials with nontrivial permeability and permittivity can be modeled using a single unknown equivalent current or field component. The integral equations result in more efficient numerical implementations and should be useful in a variety of electromagnetic applications
