Introduction Label-Free Photonic Crystal Sensors (PhC) represent an increasingly vital class of optical biosensors, designed for real-time detection of biomolecular interactions without requiring fluorescent or radioactive labels. Unlike traditional techniques that rely on tagging molecules, PhC sensors detect shifts in light behavior as biomolecules bind near a photonic structure, offering precise, non-invasive readouts. These sensors […]
Introduction Radar Absorbing Materials (RAM) are engineered to mitigate the reflection of electromagnetic (EM) waves, particularly in radar frequencies, by absorbing incident energy and converting it into negligible heat. This property significantly reduces the radar cross-section (RCS) of an object, making it less detectable to radar systems. RAMs serve as a pivotal technology in modern […]
Challenges or Open Questions While COMSOL Multiphysics 6.3 brings substantial advancements, it does not fully eliminate persistent challenges inherent to high-fidelity multiphysics simulation. One significant hurdle remains the computational demands associated with large-scale or real-time simulations. Even with the inclusion of GPU acceleration, scenarios involving fully coupled nonlinear phenomena across disparate scales often require vast […]
Even if different software tools provide necessary methods and technique to generate professional plots since they have to cater a larger audience, they prefer. to add a ton of feature that may be too much for someone who just wants to generate the academic research articles. So that is why I created the tool from […]
Mastering Chemical Reaction FEA Simulation: Pro Tips, Practical Insights & Real-World Wins : Chemical reactions are everywhere — inside your smartphone battery, in the pipelines under cities, and even in the air you breathe. But understanding how they unfold inside complex systems? That’s where things get tricky. Enter Finite Element Analysis (FEA) — the behind-the-scenes […]
AI Models Locally – You’ve seen the buzz: AI that writes your code, summarizes reports, chats like a human, and even builds full websites. But here’s the part they don’t tell you:Every time you use one of those cloud-based tools, you’re burning cash and sending your data to someone else’s servers. If you’re a solo […]
Most scientific journals have clear expectations when it comes to figure styling, particularly for plots and graphs. They typically prefer clean, minimal designs with uniform font styles such as Arial, Times New Roman, etc and font sizes that remain clearly legible after reduction—usually no smaller than 8–10 pt. Axis labels and tick marks should be […]
An Introduction to Photonic Crystal Waveguides Photonic crystal waveguides have emerged as a transformative platform in the field of nanophotonics, offering unprecedented control over the propagation of light. These waveguides are engineered from photonic crystals—periodic dielectric structures that create photonic bandgaps, analogous to electronic bandgaps in semiconductors. The periodic modulation of refractive index in these […]
Introduction to THz Photonic Crystal Fiber (PCF) Sensors Terahertz (THz) photonic crystal fibers (PCFs) have emerged as a powerful platform for sensing applications in biomedical diagnostics, environmental monitoring, chemical detection, and material characterization. The ability of THz radiation (0.1–10 THz) to penetrate non-conductive materials while being highly sensitive to molecular vibrations makes it ideal for […]
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 […]
