Polarization and Incidence Angle Independent Low-Profile Wideband Metamaterial Electromagnetic Absorber Using Indium Tin Oxide (ITO) Film
نویسندگان
چکیده
We use indium tin oxide (ITO), one of the representative resistive materials, for implementation a metamaterial electromagnetic (EM) absorber with high absorbance in wide frequency range. Highly symmetrical split ring resonators made ITO film are deposited on polyethylene terephthalate transparent and flexible features, such configuration causes proposed to be insensitive polarization incidence angles. The absorber, profile only 0.171?, exhibits wideband 7.2 GHz 27 GHz, 90% absorption criterion. A prototype is built, all computed expectations from full-wave EM simulations this work verified experimentally.

Incident Angle- and Polarization-Insensitive Metamaterial Absorber using Circular Sectors
In this paper, an incident angle- and polarization-insensitive metamaterial absorber is proposed for X-band applications. A unit cell of the proposed absorber has a square patch at the centre and four circular sectors are rotated around the square patch. The vertically and horizontally symmetric structure of the unit cell enables polarization-insensitivity. The circular sector of the unit cell ...
متن کاملAngle- and Polarization-Insensitive Metamaterial Absorber using Via Array
In this paper, we propose an angle- and polarization-insensitive metamaterial absorber. We design a metamaterial unit cell that is based on a split ring cross resonator (SRCR). We observe that the absorption frequency and absorption ratio are insensitive to incident angles when a via array surrounds the SRR. We demonstrate the effect of the via array using full-wave simulations by comparing the...
