With […]
Introduction QPSK Modulation : Quadrature Phase Shift Keying (QPSK) is a digital modulation technique central to modern telecommunications, widely employed in satellite communication, 5G mobile systems, and digital broadcasting due to its efficiency and robustness. In an era where high-speed data transmission is non-negotiable, QPSK offers a compelling solution by encoding two bits per symbol […]
Introduction Joule heating—also known as resistive or Ohmic heating—is the process by which electrical energy is converted into thermal energy as a current flows through a resistive material. This fundamental principle, rooted in the laws of electromagnetism, has far-reaching implications across electrical engineering, materials science, and industrial manufacturing. Whether in simple heating coils or advanced […]
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, […]
An Introduction to Photonic Crystal Waveguides Photonic crystal waveguides have emerged as a transformative platform in the field of nanophotonics, offering unprecedented control over the propagation of light. These waveguides are engineered from photonic crystals—periodic dielectric structures that create photonic bandgaps, analogous to electronic bandgaps in semiconductors. The periodic modulation of refractive index in these […]
Eddy current phenomena have long been understood and exploited in industrial-scale applications such as magnetic braking, induction heating, and non-destructive testing.
