In this paper we discuss fundamental considerations in the design of an electromagnetic induction (EMI) sensor. Simple circuit representations of pulsed and continuous wave EMI systems are presented and the analysis of these circuits leads one to certain conclusions regarding optimal (good) sensor design. Findings reported here are gathered from experimental research conducted over the past year and directed toward the development of an EMI system that not only has reasonable sensitivity but also has the ability to capture a target's low frequency response characteristics. The later capability is important when attempting to discriminate between low metallic content landmines and metallic clutter.
