In this paper, we proposed the high transparent digital television (DTV) antenna. The used transparent material is based on nano-structured thin film coating on the glass substrate for achieving the transparency up to 80%. The substrate dimension size of the proposed design is 200 × 150 mm2. The proposed antenna has radiation efficiency of 66.52% and having the bandwidth of 0.46–0.66 GHz. The proposed...
Finite difference time domain (FDTD) method was used to simulate the intensity distribution of an initial plane light wave incident on the surface of an optical material. When the scratch size is far less or much larger than the incident wavelength in free space, the intensity enhancement effect is not obvious and could be neglected. When the scratch size and the incident wavelength are comparable,...
