This study presents an overview of the multipath conductor concept and some recent developments of multipath conductors especially in the field of electromagnetic interference (EMI). Multipath conductors are made up of several layers of materials with different electromagnetic properties. The conductors are configured to conduct currents in parallel. These current may contain low-frequency desired currents and undesirable higher frequencies. These multipath conductors are used as a lowpass dissipative filter to reduce EMI in compact power electronics circuits by replacing the conventional filter. This new type of filtering structure has several advantages over the convention filters. The purpose of this study is to review the work done so far in terms of the analytical and software analysis of multipath conductor based EMI filters. This will create interest among the new researchers in this developing field by understanding the basic technique and applications to aid in their research further.
