Currently used materials in train windows highly attenuate the transmission of microwaves used in telecommunication and the low emissivity coating used to ensure heat insulation is opaque to these microwaves. This project aims at combining low relative permittivity (κ) with a structured laser ablation in the coating to achieve both a low attenuation of the signal and a fair pathloss imbalance between the two polarizations TE and TM for a large range of incident angles and broadband frequencies.
