Introduction: Simulation as the Backbone of Modern Semiconductor Engineering The semiconductor industry has entered an era where transistor scaling, heterogeneous integration, and system-level complexity have made physical prototyping increasingly expensive and time-consuming. In modern chip design workflows, simulation software has become indispensable for designing, verifying, and optimizing semiconductor devices and integrated circuits before fabrication. These […]

Surface plasmon resonance (SPR) is often taught as a “thin-film thickness problem”: adjust the metal thickness, add a dielectric overlayer, and the reflectance dip shifts. In practice, thickness is a relatively blunt instrument. Once you start adding anisotropic layers—birefringent dielectrics, columnar films, liquid-crystal-like coatings, 2D crystals with in-plane anisotropy, or engineered metamaterial layers—the resonance can […]
1. Introduction to Surface Plasmon Resonance (SPR) Surface plasmon resonance (SPR) refers to the resonant, collective oscillation of free electrons at a metal–dielectric interface, driven by p-polarized electromagnetic excitation under conditions that enable coupling between incident light and surface-bound charge density waves. In the canonical sensor geometry, this coupling is achieved under total internal reflection, […]
Surface-Enhanced Raman Scattering (SERS) is a powerful technique that amplifies Raman signals of molecules adsorbed on nanostructured metallic surfaces. This enhancement enables the detection of trace levels of chemical and biological species, making SERS a cornerstone in modern analytical chemistry, biosensing, and nanophotonics. In this article, we dive into the principles, simulation methodologies, and future […]
Why this question matters now We open with the modern reality: most “high-performance” SPR sensors are no longer just prism/metal/analyte. Once you add oxides, high-index films, and 2D overlayers, sensitivity can improve dramatically—but so can linewidth, drift, and fabrication sensitivity. This section frames the goal of the article: to explain what actually controls sensitivity in […]
The Quiet Revolution in Plasmonic Sensing Surface Plasmon Resonance (SPR) has long stood at the forefront of optical sensing technologies—renowned for its label-free detection, real-time analysis, and ultra-sensitivity to minute changes in the refractive index (RI) of nearby media. In biological, chemical, and environmental diagnostics, SPR sensors provide a reliable window into molecular interactions, gas-phase […]
Surface plasmon resonance (SPR) refers to the resonant oscillation of conduction electrons at a metal–dielectric interface excited by incident electromagnetic radiation under specific momentum-matching conditions. Surface plasmon–based sensors exploit this phenomenon to detect minute changes in the refractive index near the sensor surface, enabling highly sensitive, label-free detection. Within the broader category of plasmonic sensing, […]
India has taken a substantial leap forward in semiconductor technology with the launch of DHRUV64, the nation’s first fully indigenous 1.0 GHz, 64-bit dual-core microprocessor. Developed under the Microprocessor Development Programme (MDP) by the Centre for Development of Advanced Computing (C-DAC), DHRUV64 strengthens India’s microprocessor ecosystem and reduces dependence on imported chips for strategic and […]
1. Introduction: The Digital Twin of Plasmonic Sensing Surface Plasmon Resonance (SPR) represents one of the most powerful and sensitive label-free detection techniques in modern photonics. Characterized by the resonant oscillation of free electrons at a metal-dielectric interface, SPR sensors have found widespread applications in biosensing, chemical detection, and environmental monitoring. However, their development traditionally […]
