Optical Thickness of Dielectric Layer in Solar Cell Design for Improved Efficiency: A Theoretical Insight [PDF]

open access: yesPhysics Access
This study investigates the effect of varying dielectric layer thickness on the optical properties of solar cells using MATLAB. Dielectric layers with thickness ranging from 10 to 100 nm were analyzed across 200 to 1200 nm wavelengths.

Wavelength-Resolved PhotoATRP

open access: yesJournal of the American Chemical Society, 2022
The careful mapping of photoinduced reversible-deactivation radical polymerizations (RDRP) is a prerequisite for their applications in soft matter materials design. Here, we probe the wavelength-dependent behavior of photochemically induced atom transfer radical polymerization (ATRP) using nanosecond pulsed-laser polymerization (PLP). The photochemical

Motion of a Self-Propelling Micro-Organism in a Channel Under Peristalsis: Effects of Viscosity Variation

open access: yesNonlinear Analysis, 2007
The motion of a self propelling micro-organism symmetrically located in a rectangular channel containing viscous fluid has been studied by considering the peristaltic and longitudinal waves travelling along the walls of the channel.

On the biphoton wavelength [PDF]

open access: yesBrazilian Journal of Physics, 2001
We report on an experiment showing that the wavelength of a biphoton is clearly dependent on the measurement scheme and on the way it is defined. It is shown that it can take any value, depending on the control of the interferometer phase differences.

Multi-wavelength multicast wavelength assignment algorithm for limited wavelength conversion in wavelength-division multiplexing networks

open access: yesIET Communications, 2007
The multicast wavelength assignment problem in wavelength-routed wavelength- division multiplexing networks with limited wavelength conversions is addressed. A new multi- wavelength multicast wavelength assignment (MMWA) algorithm has been developed based on the multi-wavelength assignment strategy, by allowing multiple available wavelengths in a link ...
