Study of optical, thermal and radio frequency properties of low emissivity coatings with frequency selective surfaces

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