Paper Abstract

Transmission properties of bidimensional arrays of dielectric spheres are highly dependent on the size and the refractive index of the spheres and on the compactness of the array. In this paper we present the design of filters in the infrared part of the spectrum based on microspheres with high refractive index values. The design and optimization of the filters are performed using two methods: computer calculations with FDTD software and building and measuring macroscopic models of the system, in the microwave regime. We propose the design of filters of practical interest in buildings, able to remove infrared through windows, the frequencies that belong to temperatures above 25 °C.
