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 ...
Tunable perfect metamaterial absorber and sensor applications
(Springer, 2016)
Operation frequencies of traditional metamaterial absorbers are fixed meaning that it is not possible to change that frequency after the fabrication. Therefore, more studies are focused on the design of Tunable metamaterial ...
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% ...
Multifunctional metamaterial sensor applications based on chiral nihility
(Springer, 2017)
In this paper, chiral nihility based pressure, density, temperature and moisture content metamaterial sensor applications are investigated in detail. A "chiral nihility'' medium in which both the permittivity and the ...
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 ...
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 ...
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 ...
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 ...
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. ...
