infrared millimeter terahertz waves scientific conferences

We have investigated the interaction of surface plasmon polariton (SPP) mode with dipole mode at terahertz perfect metamaterial absorber (PMA) consisted of a metasurface layer, a dielectric spacer layer, and a metallic ground. The dependence of SPP modes generated by PMA on the lattice constant of the unit cell was investigated. Also, high-quality-factor resonance is observed, which has been a subject of numerous investigations since an elevated quality factor is highly desirable for the practical application
