An integrated tool for the optimal design and characterization of multilayer transparent coatings is developed. The coatings consist of thermal control films or nanometric metallo-dielectric layers. Electromagnetic shielding, optical transmittance, heat control, and thermal de-icing are the multifunctional performances of the proposed coatings. A circuit approach is developed for the prediction of the shielding effectiveness of electrically small apertures loaded with the transparent coating. The hypotheses of electrically short planar structure and large cavity are assumed. Applications of the proposed procedure are carried out to the window of a building and of a transportation aircraft. Measured and computed spectra of the shielding effectiveness and optical transmittance are presented in the radio frequency range.

Abstract
An integrated tool for the optimal design and characterization of multilayer transparent coatings is developed. The coatings consist of thermal control films or nanometric metallo-dielectric layers. Electromagnetic shielding, optical transmittance, heat control, and thermal de-icing are the multifunctional performances of the proposed coatings. A circuit approach is developed for the prediction of the shielding effectiveness of electrically small apertures loaded with the transparent coating. The hypotheses of electrically short planar structure and large cavity are assumed. Applications of the proposed procedure are carried out to the window of a building and of a transportation aircraft. Measured and computed spectra of the shielding effectiveness and optical transmittance are presented in the radio frequency range.Pubblicazioni consigliate
