Leptospirosis is an illness caused by a Leptospira bacterial infection, and it can be fatal if not
correctly diagnosed and treated. This work explores the development of an optical biosensor …

Scattering by particles significantly smaller than the wavelength is an important physical
process in the icy and rocky bodies in our Solar System and beyond. A number of …

In this paper, we report on the development of DNA biosensor using carbon quantum dots
(CQDs) to enhance Leptospira DNA detection. Leptospira is a bacterium that invades …

Within the accuracy of the first-order Born approximation, sufficient conditions are derived for
the invariance of spectrum of an electromagnetic wave, which is generated by the scattering …

In the present work, the Talbot effect of a square grating is analyzed when light is reflected
from a rough surface. It is shown theoretically that the scattered light intensity in the Fresnel …

We report here a detailed experimental study to demonstrate the effect of source spectral
characteristics such as spectral bandwidth (Δλ), peak wavelength (λ_0), and shape of the …

Mirage is a fascinating phenomenon that has attracted many scientists to report their
observations and descriptions about it. There are two different approaches to mirage …

In this work, a linear grating is used to project a periodic light intensity distribution on a rough
interface, and the near field transmitted light scattering is studied. It is shown theoretically …

Imposing a phase random distribution in an interval larger than 2 π on a spatially coherent
light beam transforms the beam into a diffuse one. However, if the required random phase …

Scattering by particles significantly smaller than the wavelength is an important physical
process in the rocky bodies in our solar system and beyond. A number of observations of …
