Abstract
Illustrative embodiments disclosed herein pertain to a thermal imaging system that includes a thermal imaging sheet having an array of thermal unit cells for generating a thermal footprint in response to receiving an RF signal. The thermal footprint is composed of an array of hotspots having a first set of hotspots indicative of a radiation characteristic of a first polarization component of the RF signal, and a second set of hotspots indicative of a radiation characteristic of a second polarization component of the RF signal. Each thermal unit cell includes a first RF antenna and a second RF antenna oriented orthogonal with respect to each other. The first RF antenna includes a terminating resistor that generates a hotspot among the first set of hotspots and the second RF antenna includes another terminating resistor that generates a hotspot in the second set of hotspots.
