Accurate Simulation of Shielding Effectiveness of Metallic Cabins Using an Improved Calderón Preconditioner-Based Time-Domain Integral Equation Method

An efficient simulation of shielding effectiveness of some metallic cabins or enclosures is performed using an improved Calderón preconditioner-based time-domain integral equation method. During its implementation, Rao-Wilton-Glisson and Buffa-Christiansen functions are used as the spatial basis functions for solving the Calderón preconditioned time-domain electric field integral equation, which g...
