All conductors are assigned with a finite conductivity of 58 MS·m−1 and the FPRFS substrate is modeled using FR-4 epoxy material in HFSS SysLibrary. The coaxial cable and SMA connector dielectrics are modeled using Teflon material. Waveport is used to excite the system. Prototype ...
The frequency separation between F2 and F3 can be reduced to zero by reducing the amplitude of the square-wave voltage or be increased to a maximum by increasing that voltage. It can, therefore, be seen that variations of amplitude of M will shift only one band of frequencies (F3 to F4)...
