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 […]

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 […]

Eddy currents are circulating currents induced within conductors when they experience a changing magnetic field. These currents arise due to electromagnetic induction, following Faraday’s Law, and are opposed by Lenz’s Law, which states that the induced current will flow in a direction that opposes the change causing it. This phenomenon is particularly significant in electrical […]

Thermoelectric modeling involves simulating the direct conversion of heat energy into electrical energy (and vice versa) using numerical methods like Finite Element Analysis (FEA). This approach enables engineers and researchers to design, optimize, and validate thermoelectric devices such as thermoelectric generators (TEGs), Peltier coolers, and energy harvesting systems. FEA helps in solving complex multi-physics interactions […]

Supercapacitors, also known as electrochemical capacitors or ultracapacitors, have gained significant attention due to their ability to store and deliver energy at high power densities. They bridge the gap between conventional capacitors and batteries, offering rapid charge/discharge cycles with long operational lifetimes. To understand and optimize supercapacitors, numerical simulation is crucial. COMSOL Multiphysics provides a […]

Optical simulations play a crucial role in designing photonic devices, waveguides, laser systems, and other light-based technologies. Whether you’re developing a photonic crystal biosensor or optimizing a fiber optic communication system, simulations allow you to predict how light interacts with materials—before committing to expensive prototyping. One of the most powerful tools for optical simulations is […]
