Abstract
In this work, the shielding properties of mesh structures with various cell sizes on a K108 glass substrate are studied. The transmission spectra of the samples were obtained in a frequency range from 1 GHz to 1620 THz. A comparison of the experimental transmission spectra with those obtained using several theoretical models, and a numerical calculation were carried out. The most optimal theoretical model used to describe the shielding properties of a mesh structure in the frequency range upper-bounded by a resonant frequency is the one-mode calculation model. Anti-reflection coatings were used to increase the transmission coefficient of the structures in the visible and near-IR spectral ranges. These mesh structures can be used to shield optoelectronic devices such as a video camera or a laser rangefinder from microwaves.
Highlights
With the development of electronic wireless devices, the problem of shielding from microwaves (300 MHz–300 GHz) is becoming increasingly important for the operation of electronic devices
Shielding of optoelectronic devices (OEDs) from this electromagnetic radiation is a part of scientific and practical tasks involved in electromagnetic compatibility (EMC), which means maintaining the useful characteristics of objects under the condition of irradiation by microwaves
The electromechanical parts of OEDs are successfully protected from microwaves by a metal housing, while the optical elements require smart shielding
Summary
With the development of electronic wireless devices, the problem of shielding from microwaves (300 MHz–300 GHz) is becoming increasingly important for the operation of electronic devices. The electromechanical parts of OEDs are successfully protected from microwaves by a metal housing, while the optical elements require smart shielding. Various methods make it possible to achieve effective shielding from parasitic radiation via the reflection or absorption of electromagnetic waves. Despite such a variety of different types of shielding structures, free-standing conductive mesh structures are currently used because of their low weight, flexibility, and effective shielding from microwaves Such filters have been studied sufficiently, and analytical formulas are available to predict the most important optical, electrical, and microwave properties. Searches for a solution to OED shielding from microwaves are being carried out mostly by using various nontraditional materials to form conducting layers (e.g., ITO films [1]) or by applying various surface designs [10,11]
