Overview: Study of magnetization temperature in ferromagnetic crystals

EuO and EuS Materials are used in study. As per Weiss mean field approximation (MFA), below certain critical temperature(Tc) ferromagnetic materials have spontaneous magnetization — i.e., a sizable macroscopic magnetic moment even in the absence of an external magnetic field. The effective field acting...

Summary of Article: The topological aberrations of twisted light

 Topology describes the study of properties of spaces that are invariant under any continuous deformation.Topological aberration: It contains a high-order optical vortex which experiences not only geometrical shifts, but an additional splitting of its high-order vortex into a constellation...

Summary of Article: Temporal signal processing method for optical metasurfaces

The temporal signal: Temporal signal varies with time. It is used to identify patterns, or changes in audio signals, video frames, or sensor readings. In optics, it is used for shaping, filtering, or differentiating light signals to data transmission or image processing.The metasurface is very thin...

Summary of Article Related to How Taylor Series is used in Non linear time-varying systems

 The time-varying system is approximated as a polynomial function of time, enabling the derivation of a time-varying control law.Nonlinear Time-Varying Systems (NLTV): These systems are difficult to control due to their complexity. Traditional methods such as linearization scheduling transform...

Use of Taylor series and Fourier Transform

(Digital Image Correlation-DIC is a non contact technique to measure the surface displacement of a specimen by comparing digital images taken at different stages of deformation)1. Taylor Series vs. Direct Fourier Transform: The paper introduces the Taylor series image reconstruction method, which increases efficiency over the conventional DFT-based method. Using third- and fourth-order Taylor series...
