Abstract :
This paper presents an efficient technique to evaluate the propagation characteristics of PCB traces with periodic roughness. This technique is based on the application of the array-scanning-method finite-different time-domain technique in which only a single periodic element needs to be modeled. Numerical examples are used to demonstrate the effectiveness and efficiency of this approach.
