In this paper, a new concept of adding a band-stop frequency-selective surface (FSS) to suppress spurious emissions from a spiral inductor is proposed. These emissions are especially serious, when the inductor has a wide impedance-matching band. The

A simplified closed-form equation for microstrip lines radiation is applied for calculating electromagnetic interference(EMI) problems on printed circuit board (PCB). Conventionally, radiation problems have to resort to full wave simulators. However,
