Paper Abstract

There are currently four types of transparent electrically conductive filters available. These are

(1) a free-standing conducting inductive mesh,

(2) a substrate coated with a conducting inductive mesh,

(3) a conducting substrate,

and, (4) a substrate coated with a continuous conducting coating.

Each can be designed to provide high visible, near infrared, and/or far infrared transmittance and high radio frequency (RF) and microwave reflectance. Itek has developed theoretical models to predict the performance of each filter type at optical and very long wavelengths as a function of pertinent design features such as conductivity, electronic mobility, thickness, mesh period and line width. The temperature dependence is explicitly included. This paper presents Itek’s methods for predicting the performance of these four filter types at both optical and RF frequencies.
