Microwave surface plasmon polariton-like sensor based on half-mode substrate integrated waveguide for highly sensitive dielectric constant detection

Microwave sensors have attracted a considerable attention since they can provide non-invasive, label-free, and real-time detection; however, they often suffer from low sensitivity and resolution. In this paper, we present a novel highly sensitive microwave sensor based on half-mode substrate integrated waveguide (HM SIW) that supports surface plasmon polariton (SPP)-like propagation.
