We report some of our recent progress in enhancing the extraordinary optical transmission (EOT), perfect absorption and field squeezing. Based on the excitation of surface plasmon waves in optical nano-antennas, the extraordinary transmission of light through a vertical nano-slit in a metal film is realized. Omni-directional, broadband and polarization-insensitive absorption of light is achieved in a thin metamaterial absorber which consists of cross-antennas and a metal ground. A dielectric split ring inside a permeability-near-zero metamaterial is used to squeeze electromagnetic energy and obtain strong magnetic field at the gap without using any resonance mechanism.
