Abstract
Abstract The paper considers reservation structure implemented by using modal filtering. Such reservation is called modal reservation (MR) for short. To ensure certainty, we took a PCB layout with a single MR. It is shown that in quasi-static simulation, for the structure with losses in conductors and dielectrics, the cut-off frequency for an OC and an SC at one end of the passive conductor is 5.5 and 1.6 %, respectively, lower than for the circuit in operating condition, and the resonance frequencies are 8 and 11.6 %, respectively, lower. In electrodynamic simulation, for the conductor-loss structure and dielectrics, the cut-off frequency for an OC and an SC at one end of the passive conductor is 1.3 and 2.7 %, respectively, lower than for the circuit in operating condition, and the resonance frequencies are 7.3 and 10.65 % lower. The differences of resonance frequencies ( f 0 ), cut-off frequencies ( f cu ) in quasi-static and electrodynamic simulations are no more than 5.66 and 1.6 %, respectively.
