Summary:A polarization electric field integral equation (EFIE) is used to model conducting discontinuities in a dielectric slab waveguide. A complex refractive index rigorously accounts for the effects of conduction current in the discontinuity region. Both dissipative and active cases are treated. Power balance, based on Poynting's theorem, is used to determine the fractional radiated power in each case. The method of moments is invoked to solve the integral equation. The accuracy of the analysis method is confirmed through comparison of results for the air gap case with those of previously published methods. Numerical results illustrate an application to a typical GaAs ternary system.< >
