In this paper, a miniaturized MIMO antenna for smart glasses is proposed. The proposed MIMO antenna is designed using T-shaped isolator inserted between two closely located Inverted-F Antenna and using two slots located in the ground for isolation enhancement and impedance matching characteristic. The proposed antenna has only the overall dimensions of 35mm×9mm×0.8mm and operates in the 2.4 GHz ISM...
We report on exposing a photosensitive zinc phosphate glass containing silver to different radiation (electron, gamma, optical). Laser irradiations using nanosecond ultraviolet (UV) and femtosecond infrared (IR) laser are compared with gamma and electron exposure. All irradiated glasses exhibit absorption maxima around 320nm and 380nm and emission in the visible spectral range. Following exposure,...
Laser structuring and electro-poling has been carried out in silver containing glasses. The second-order NLO response after direct laser patterning has been investigated in the scope of developing further practical use of the material.
Ultra-fast laser-induced positive refractive index changes in bulk tellurite glass were investigated. The refractive indexes of waveguiding structures were measured using the far-field approach. Filamentation was observed for certain irradiation conditions.
