Electromagnetic scattering simulations using equivalent boundary condition models
Equivalent boundary condition models are one approach to simplifying electromagnetic (EM) scattering problems while retaining a high degree of solution accuracy in the domain of interest. These models are successful when the dominant EM characteristics of the scattering body are captured within the model, and they are robust when the parameters in the model are capable of adjustment, in a systematic manner, to accurately simulate the scattering for physical variations in the target. Both of these properties are successfully integrated in this work to model two important classes of scatterers used in the modern low observable vehicle: dielectrically filled cavity-backed apertures and periodic structures at lower frequencies.
