TRANSIENT TIME-DEPENDENT ELECTRIC FIELD OF DIELECTRIC BODIES USING THE VOLTERRA INTEGRAL EQUATION IN THREE DIMENSIONS

An accurate and flexible three-dimensional Volterra Time Domain Integral Equation (TDIE) algorithm is presented and implemented here to model the time-dependent electromagnetic field of arbitrarily shaped dielectric bodies. This development is motivated by the need for a modern high-resolution numerical tool that is capable of providing a full and comprehensive investigation of devices containing a diverse range of feature sizes or boundaries, in all three space dimensions plus time. Stability, accuracy and convergence of the algorithm are discussed and verified by means of canonical working examples.
