Delta-gap port model for surface-volume-surface electric field integral equation
… Electric Field Integral Equation (SVS-EFIE). The SVS-EFIE is a class of single-source integral equations (SSIEs), which is obtained from the combination of the volumetric equivalence principle with the conventional single-source eld representation. The classical delta-gap port model is …

On improving the low-frequency performance of full-wave modeling techniques
"The method of moments and the finite element method are very powerful methods for solving electromagnetic problems in the frequency domain. However, the direct application of these techniques at low frequencies results in instability and significant errors. This is due to the divergence operation …
