Metasurface absorbers

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 […]

Why Your Next Design Needs FEA Simulation to Succeed

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 […]

Simulation of Radar Absorbing Materials : Advancements, Challenges, and Future Prospects

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 […]
