Mixed discretization of the time-domain MFIE at low frequencies
IEEE Antennas and Wireless Propagation Letters, 2017•ieeexplore.ieee.org
Solution of the magnetic field integral equation, which is obtained by the classical marching-
on-in-time (MOT) scheme, becomes inaccurate when the time-step is large, ie, under low-
frequency excitation. It is shown here that the inaccuracy stems from the classical MOT
scheme's failure to predict the correct scaling of the current's Helmholtz components for
large time-steps. A recently proposed mixed discretization strategy is used to alleviate the
inaccuracy problem by restoring the correct scaling of the current's Helmholtz components …
