Introduction Laser pulse simulations are essential for understanding ultrafast optical interactions, nonlinear effects, and photonic device performance. In finite element analysis (FEA) and finite-difference time-domain (FDTD) simulations, setting up a laser pulse involves defining temporal and spatial characteristics of the pulse, ensuring correct boundary conditions, and incorporating the interaction with the material properties.

Introduction Metasurface absorbers are an emerging class of artificially structured materials engineered at the sub-wavelength scale to achieve near-perfect absorption of electromagnetic waves. These structures manipulate incident radiation through carefully designed geometric patterns and material compositions, enabling strong, frequency-selective, and often tunable absorption capabilities. Unlike traditional bulk absorbers, metasurface absorbers are compact, lightweight, and can […]
Introduction Metasurfaces are ultra-thin, artificially structured materials designed to manipulate electromagnetic waves in unprecedented ways. Unlike conventional optical components that rely on gradual phase accumulation through bulky media, metasurfaces engineer abrupt changes at subwavelength scales using nano-patterned “meta-atoms.” These structures grant remarkable control over amplitude, phase, and polarization, opening a new frontier in optics, sensing, […]
Introduction Photonic crystal (PhC) biosensors have emerged as vital tools in the landscape of cancer diagnostics, primarily due to their ability to offer high sensitivity, rapid response, and label-free detection. These sensors operate on the principle of manipulating light through periodic dielectric structures that produce photonic bandgaps. Variations in local refractive index—such as those caused […]
Introduction FEA Simulation is a computational method used to predict the behavior of structures and systems under real-world physical conditions. By solving complex partial differential equations (PDEs) over discretized domains, FEA allows engineers to simulate stress, heat transfer, fluid dynamics, and more—well before a physical prototype is built. As industries continue to evolve under the […]
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 […]
Introduction Surface Plasmon Resonance (SPR) sensors have emerged as powerful tools for label-free, real-time detection of biomolecular interactions. Their operational basis lies in monitoring shifts in the refractive index at a metal-dielectric interface, which correlates directly with molecular binding events occurring on the sensor’s surface. This capability has propelled SPR sensors into critical roles across […]
Introduction Electronic Design Automation (EDA) simulations have become a fundamental pillar in modern electronics and semiconductor design. As electronic systems grow in complexity, the need for tools that can manage, validate, and optimize intricate circuit layouts and chip architectures has become paramount. At its core, EDA simulation refers to the use of computational models to […]
Introduction Semiconductor simulation represents a fundamental shift in how electronic devices are conceived, designed, and validated. As devices shrink to nanometer scales and integrate multifaceted physical phenomena, the use of software like COMSOL Multiphysics—specifically its Semiconductor Module—has become indispensable. Semiconductor simulation entails the numerical solution of complex physical equations to predict how devices will behave […]
Introduction Semiconductor simulation refers to the computational modeling of semiconductor devices and fabrication processes. These simulations span a vast landscape—from electron transport and thermal diffusion at the nanoscale to large-scale design rule verification—enabling engineers to analyze, predict, and optimize device behavior long before physical fabrication begins. As Moore’s Law continues to approach its physical limits, […]
