ECRH mode: Advanced Simulation and Analysis of High-Power Microwave & Millimeter-Wave Beams

by

1. Introduction: Modeling High-Power Electromagnetic Beams The precise generation, transmission, and manipulation of high-power microwave (HPM) and millimeter-wave (MMW) beams are critical for a range of advanced scientific and industrial applications. These include plasma heating in fusion energy research (like Electron Cyclotron Resonance Heating – ECRH), directed energy systems, high-resolution radar, industrial material processing, and … Read more

Unveiling Wave Wonders: Simulating Interference with GPU Power

by

Our world is alive with waves – from the gentle ripples on a pond to the invisible carriers of sound and light. When these waves meet, they don’t simply pass by; they interact in a mesmerizing dance of reinforcement and cancellation, a phenomenon known as interference. This principle is fundamental, shaping how we perceive sound, … Read more

Dockerizing Your Web Application on Debian and Sharing via Docker Hub

by

In modern software development, deploying applications consistently across different environments (development, testing, production) is crucial. Differences in operating systems, system libraries, or installed package versions can lead to the infamous “it works on my machine” problem. Docker solves this by allowing you to package your application, along with all its dependencies and required system configurations, … Read more

An Interactive Smith Chart with Manual & Auto Matching
