Experimental determination of the performance of rice husk-carbon nanotube composites for absorbing microwave signals in the frequency range of 12.4-18 GHz
(EMW Publishing, 2013)
Composites of rice husks and carbon nanotubes (RHC-NTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant ...
Improvement of absorption characteristics of solar cell above room temperature using quantum dot
(Engg Journals Publications, 2013-10)
This paper presents a theoretical study on the light absorption characteristics of solar cell. We have analyzed the temperature dependence of the absorption coefficient of light and the percentage of the incident light ...
Optical properties of ultraphosphate glasses containing mixed divalent zinc and magnesium ions
(Elsevier, 2013-01)
Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x(MgO)30−x(P2O5)70 were prepared by melt quenching technique in the range of 5 ⩽ x ⩽ 20 mol%. The optical absorption spectra of the glasses were measured ...
The influence of human head model wearing metal-frame spectacles to the changes of SAR and antenna gain: Simulation of frontal face exposure
(EMW Publishing, 2013)
The relationship between specific absorption rate (SAR) and antenna gain inside the head due to the metal-frame spectacles was investigated. The radio frequency (RF) energy source considered is the smartphone used in the ...
