New generation chiral metamaterials with small and flat chirality over a certain frequency band based on circular split ring resonators for microwave filter applications
(World Scientific Publishing Co. Pte Ltd, 2016)
There are many studies in literature on chiral metamaterials (MTMs) to obtain large chiralities with dynamic optical activities. With this regard, this new generation planar chiral MTM study focuses on a small, non-dispersive ...
Linear to left- and right-hand circular polarization conversion by using a metasurface structure
(Cambridge University Press, 2018)
By using a metasurface (MS) structure, a linearly polarized wave is converted to circularly polarized waves. Both right- and left-handed circular polarizations (RHCPs and LHCP) are obtained by a simple configuration in the ...
Broad-band polarization-independent metamaterial absorber for solar energy harvesting applications
(Elsevier, 2017)
A novel broad-band polarization-independent with wide-angle metamaterial absorber(MA) is investigated and demonstrated for solar energy harvesting applications. The proposed MA is composed of two metal layers which have ...
Broad band MA-based on three-type resonator having resistor for microwave energy harvesting
(Taylor and Francis Inc., 2017)
We proposed metamaterial absorber having multi-type split coin resonator based on resistive loads. The numerical simulation results and experimental measurements indicate that broad band absorption with a ratio over 80% ...
Tunable perfect metamaterial absorber design using the golden ratio and energy harvesting and sensor applications
(Springer, 2015)
We present the design, characterization, theoretical and experimental verification of a tunable perfect metamaterial absorber (MA) based electromagnetic (EM) energy harvesting and sensor application. We have used the golden ...
90° degrees Polarization rotator and antireflector using meanderline chiral metamaterials: Analytical and numerical approach
(Elsevier GmbH, 2015)
We demonstrate theoretically and numerically a chiral slab that can exhibit optical activity, circular dichroism, and antireflection in detail. Copolar and crosspolar transmitted and reflected waves depending on permittivity, ...
Smart monopole antenna with pattern and frequency reconfiguration characteristics based on programmable metasurface
(Wiley, 2019)
Metasurfaces having ultrathin and planar structure with sub-wavelength unit cell, have recently gained significant potential for use thanks to their control capabilities over the electromagnetic waves from microwave to 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 ...
Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator
(Springer, 2017)
A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. ...
