A boundary integral equation formulation is presented for the electromagnetic\ntransmission problem where an incident electromagnetic wave is scattered from a\nbounded dielectric object. The formulation provides unique solutions for all\ncombinations of wavenumbers in the closed upper half-plane for which Maxwell's\nequations have a unique solution. This includes the challenging combination of\na real positive wavenumber in the outer region and an imaginary wavenumber\ninside the object. The formulation, or variants thereof, is particularly\nsuitable for numerical field evaluations as confirmed by examples involving\nboth smooth and non-smooth objects.\n
