A Gradient-Divergence Operator Regularized Electromagneto-Quasistatic Field Formulation

Electromagneto-quasistatic field formulations model resistive, capacitive, and inductive effects, while disregarding wave propagation. When such formulations are expressed in terms of a magnetic vector potential and of a scalar electric potential, uniqueness of solutions requires additional gauging constraints, on top of suitable initial and boundary data. Here, a gauging based on a addition of discrete gradient-divergence operator is presented for electromagneto-quasistatic frequency-domain field formulations, in the context of H (curl)-conforming finite elements, and is numerically verified.
