Tunable energy harvesting on UHF bands especially for GSM frequencies
(Cambridge University Press, 2018)
Metamaterial-based energy harvesting structures operating at GSM goo and GSM 1800 frequency bands have been proposed. The basic structure is composed of four nested U-shaped elements on the front and back side of the ...
Design of a Dual Band Metamaterial Absorber for Wi-Fi Bands
(American Institute of Physics Inc., 2018)
The goal of this work is to design and fabrication of a dual band metamaterial based absorber for Wireless Fidelity (Wi-Fi) bands. Wi-Fi has two different operating frequencies such as 2.45 GHz and 5 GHz. A dual band ...
Zinc oxide-tungsten-based pyramids in construction of ultra-broadband metamaterial absorber for solar energy harvesting
(Institution of Engineering and Technology, 2017)
A new broadband absorber is investigated for the entire frequency domain of solar light (infrared, visible light and ultraviolet). While current absorbers in the literature have limited operation frequencies, investigated ...
Dynamical chiral metamaterial with giant optical activity and constant Chirality over a certain frequency band
(Applied Computational Electromagnetics Society (ACES), 2016)
We demonstrate numerically and experimentally a dynamical chiral metamaterial that uniaxially creates giant optical activity and circular dichroism. In addition, the structure gives a high negative refractive index due to ...
Electromagnetic simulations of polarization-insensitive and wide-angle multiband metamaterial absorber by incorporating double asterisk resonator
