Top Applications of Surface Plasmon Resonance Sensors (SPR Sensors): SPR sensors have revolutionized the field of chemical and biological sensing by providing real-time, label-free detection of molecular interactions with exceptional sensitivity. The working principle of an SPR sensor relies on the excitation of surface plasmons—coherent oscillations of free electrons—at the interface between a metal (typically […]
At first glance, a silicon slab perforated with a regular pattern of holes might resemble an artistic experiment in nanofabrication. But when light is introduced into this holey structure, something extraordinary happens: the slab becomes a playground for photons, bending, trapping, and guiding them in ways that defy classical intuition. This is the essence of […]
Eddy current phenomena have long been understood and exploited in industrial-scale applications such as magnetic braking, induction heating, and non-destructive testing. However, with the miniaturization of devices and the increasing need for precise sensing technologies, eddy currents have emerged as a pivotal mechanism in the design and operation of microelectromechanical systems (MEMS) and microsensors. At […]
OAM Modes in Fiber : Optical fibers support different types of modes depending on their refractive index profile. In step-index fibers, the fundamental modes are linearly polarized (LP), but in ring-core fibers (RCFs), the natural modes are hybrid modes, specifically HE (hybrid electric) and EH (hybrid magnetic) modes. These modes arise due to the vector […]
Laser ablation is a process in which a high-intensity laser beam removes material from a solid surface through various thermophysical mechanisms, including melting, vaporization, and plasma formation. Understanding and modeling laser ablation using Finite Element Analysis (FEA) requires solving complex heat transfer and phase transition equations to capture the dynamic response of the material under […]
Maxwell’s equations form the foundation of classical electromagnetism, providing a rigorous mathematical framework for understanding the interaction of electric and magnetic fields. These equations, formulated by James Clerk Maxwell in the 19th century, unified the concepts of electricity and magnetism into a single theory, leading to groundbreaking discoveries, including the prediction of electromagnetic waves. The […]
The AI world is buzzing with excitement, and rightfully so. From OpenAI’s ChatGPT to Google’s Gemini, artificial intelligence has made huge strides. But what if I told you that building a ChatGPT competitor isn’t as impossible as it seems? In fact, I built one in just 30 minutes—and I’m going to reveal exactly how I […]
Surface Plasmon Resonance (SPR) is a fundamental phenomenon in plasmonics that arises from the collective oscillations of conduction electrons at the interface between a metal and a dielectric. These oscillations are excited by incident electromagnetic waves under specific conditions, leading to enhanced electromagnetic fields and strong optical absorption. SPR is widely used in biosensing, nanophotonics, […]
FEA optimization using Deep Learning: Finite Element Analysis (FEA) is a widely used computational method for solving structural, thermal, and fluid dynamics problems in engineering. However, traditional FEA methods are computationally intensive, particularly for optimization tasks that require multiple simulations. Recent advancements in Deep Learning (DL) have shown immense potential in accelerating FEA, reducing computational […]
