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% ...
Exhibition of polarization conversions with asymmetric transmission theory, natural like chiral, artificial chiral nihility and retrieval studies for K- and C-band radar applications
(Indian Academy of Sciences, 2019)
In this study, asymmetric transmission, natural chirality phenomena and a retrieval study with chiral metamaterials (MTMs) are numerically and experimentally focussed, investigated and discussed by examining the polarization ...
Octagonal Shaped Metamaterial Absorber Based Energy Harvester
(Kaunas University of Technology, 2018)
In this study, a novel octagonal shaped metamaterial based broadband absorber is proposed for energy harvesting at WIMAX wireless communication band. The proposal has an absorption of 99.97 % at 5.5 GHz with a bandwidth ...
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 ...
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 ...
