Investigation and Simulation of the Effect of ElectronicCircuit Board Tracks on the interference of EM wavesOnto Active Transistor Circuits

Microstrip lines and tracks of Printed Circuit Boards (PCBs) have definitive effects on the electromagnetic wave induction and interference on boards. In this paper the effect of changes in the physical characteristics of conductive lines and PCBs was simulated three dimensionally using Finite Difference Time Domain (FDTD) method. The length and width of a microstrip line and thickness of PCB are among parameters that variation effects of which are presented using simulation. High power Electromagnetic radiation effect on a transistor amplifier is also investigated by introducing corresponding electromagnetic equations into the simulation software using BJT GP model
