Performance enhanced absorbing boundary condition for electromagnetic modelling and simulation

“…[1][2][3] Among numerous advantages of the FDTD algorithm, one of the most important advantages is that the waveform can be directly obtained in the wide bandwidth problems. 1 Moreover, compared with the other full-wave simulation algorithms, the FDTD algorithm can obtain considerable computational efficiency during the simulation. 4 To simulate the open region problems, one of the most intractable difficulties is to efficiently absorb the outgoing waves and reduce the wave reflections.…”

EMI effect simulation of braided cable network using a hybrid FDTD method

“…Taking transmission line (TL) network in a real environment into account detailly, the simulation process will be very complex. In the rapid progress in computational EM solvers, the finite‐difference time‐domain (FDTD) remains a popular choice for solving EMI problems with complex geometry and inhomogeneous medium . However, the primary shortcoming of staircase error restricts its applicability in handling the interaction of EM waves with complex objects incorporating small features and multi‐level coupling paths.…”

“…In the rapid progress in computational EM solvers, the finite-difference time-domain (FDTD) 3 remains a popular choice for solving EMI problems with complex geometry and inhomogeneous medium. [4][5][6][7] However, the primary shortcoming of staircase error restricts its applicability in handling the interaction of EM waves with complex objects incorporating small features and multi-level coupling paths. Thus, several modified FDTD methods have been proposed to take hybrid EMI effects of different coupling paths into account by combining the Maxwell's equations, TL equation, and circuit theory together.…”

Electromagnetic responses of a metallic conical frustum cabin with one coaxial feeding monopole antenna

“…For example, finite-difference time-domain (FDTD) method, as demonstrated in [8], has been used for capturing cable-induced transient responses in some metallic rectangular enclosures, together with their shielding effectiveness (SE) [9,10]. On the other hand, it is well known that coaxial cables have often been used for feeding various antennas, and their FDTD models for feeding monopole ones have been studied by some researchers recently [11][12][13]. For example, both equivalent feeding and direct telegraph equation models have been proposed in [14,15], respectively, which are helpful for further studying transient responses of some more complex structures with multi-scale features.…”
