Abstract: In this paper, the Geometric Optics (GO)/Physical Optics (PO) method is improved to analyze the terahertz (THz)-wave scattering characteristics of objects with multiple small-scale grooves, ...
In an ideal case, optical rays refracting through a spherical lens can be made to converge at a single point known as the focal point. However, in practice, rays fail to converge at a single point and ...
Through JEE Advanced, the IITs provide admission to undergraduate programmes that culminate in a Bachelor’s degree, an Integrated Master’s degree, or a Bachelor-Master Dual Degree in fields such as ...
Abstract: We propose a novel method to calculate the electromagnetic (EM) wave propagation from low-earth orbit satellite (LEO) to a ground station based on the physical optics (PO), ray tracing ...
