Imagine you just moved to a new home or are renting a place for a weekend trip. A visual inventory can help you figure out where the refrigerator, TV, and even some security cameras are, but what if there are additional, hidden, electronic devices that were left behind by others? This paper focuses on detecting electronic devices, all of which have circuit elements and specific properties that are unique to these circuit elements. By illuminating these elements with a unique radar, we show that the presence of devices can be detected.
