The high sensitivity of Lorentz sensors comes from its narrowband resonant characteristics marked by rapid slope change of slope of its phase spectrum, a phenomenon known as Anomalous dispersion. Unlike conventional microwave resonant sensors which have a resonant amplitude, the Lorentz sensors also...
