Introduction The simulation of numerical laser pulses within the context of Finite Element Analysis (FEA) has emerged as a crucial focus in both academic research and industrial innovation. This involves modeling how discrete, high-energy laser pulses interact with materials to induce localized heating, melting, ablation, or even structural transformation. Unlike continuous wave lasers, pulsed lasers […]
Laser sources play a critical role in numerical simulations across various fields, including photonics, material processing, biomedical optics, and optical communication. In Finite Element Analysis (FEA) and Finite-Difference Time-Domain (FDTD) simulations, different types of laser sources are modeled to study their interaction with matter, wave propagation, and nonlinear effects.

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 Local AI app development refers to the practice of building and executing AI applications directly on personal or on-premises hardware rather than utilizing remote cloud services. This shift reflects the growing demand for enhanced privacy, cost-efficiency, and greater control over data and model behavior. As open-source large language models (LLMs) such as DeepSeek gain […]
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 […]
