IntroductionTamm-plasmon-polaritons (TPPs) are optical surface states that arise at the interface between a metallic film and a photonic crystal (PC). Unlike traditional surface plasmon polaritons (SPPs), which require specific conditions for excitation (such as total internal reflection in a prism-coupled system), TPPs can be directly excited in normal incidence configurations, making them ideal for biosensing […]

Photonic crystals (PhCs) are periodic dielectric structures that affect the motion of photons in much the same way that the periodic potential in a semiconductor crystal affects electrons. The ability of photonic crystals to create photonic band gaps (PBGs) has led to numerous applications, including optical filters, waveguides, and more recently, sensors. Among the various […]
