Resumen: The use of frequency selective surfaces (FSSs) defined on railcar windows with a metallic low-e coating to improve the reception of mobile communications signals is becoming ever more common. The proximity of the glass to the passenger in this scenario has introduced a new parameter to consider, aesthetics. This paper presents a complete study of the development of a FSS defined by laser ablation, considering all current requirements. The fabricated samples will be characterized in the optical and radiofrequency ranges of the spectrum. Also, by means of an electron microscope, the chemical elements of each area of the samples will be quantified, in order to study the ablation process. New samples will be made using these parameters, and its performance according to specifications verified. These data will be correlated, using digital image processing, to the aesthetic impact of the engraved FSS, as confirmation of the optimal laser configuration.
