VoltOne

### Classical Electrodynamics & Electromagnetic Field Engineering Workbench Explore classical electrodynamics calculations in a focused 3-tier Apple-native engineering workbench. VoltOne covers 19 closed-form analytical modules across 6 core sections (Electrostatics, Magnetostatics, Waves, Radiation, Relativity, and Reference), organizing numbered step-by-step input cards, field-profile plots, structured result tables, a contextual right-hand Inspector (`Symbols`, `Choices`, `Assumptions`), and an interactive plane-wave phase illustration. #### 【6 Core Sections · 19 Electrodynamics Modules】 - **Electrostatics (6 Modules)**: Point Charges (`E` and `V` superpositions), Gauss's Law (5 symmetric closed-form geometries), Multipole Expansion, Method of Images (grounded plane and sphere), Capacitance & Energy, and Dielectrics. - **Magnetostatics (4 Modules)**: Biot-Savart Law (7 current-source geometries), Ampere's Law, Inductance & Magnetic Energy, and Magnetic Materials. - **Electromagnetic Waves (5 Modules)**: Plane Waves (with interactive `E`, `B`, `S` phase teaching canvas), Waves in Conductors (skin depth and phase lag), Rectangular Waveguide (`TE_mn` cutoff and dispersion), Reflection & Transmission (Fresnel equations, Brewster and critical angles), and Lorentz Dispersion. - **Radiation (2 Modules)**: Dipole Radiation (electric and magnetic dipoles) and Moving Point Charge (Larmor power, Liénard relativistic parallel/perpendicular/vector radiation, and Abraham-Lorentz reaction). - **Relativity (1 Module)**: Moving Frames (Lorentz boost of `E` and `B`, field invariants, velocity addition, and Lorentz factor). - **Reference (1 Module)**: Live bidirectional `SI ↔ Gaussian` unit conversion and fundamental physical constants. #### 【Refined Workbench & Embedded Manuals】 - **3-Tier Progressive Architecture**: Module sidebar + numbered workflow cards (`1` -> `2` -> `3` -> `4`) + live contextual Inspector (`Symbols`, `Choices`, `Assumptions`). - **Dual Embedded English PDF Manuals**: Read the bundled English User Manual and Theory Manual with chapter outlines, module jump links, and PDF export. - **8-Language Interface Switcher**: Instant toolbar switching between English, Simplified Chinese, Traditional Chinese, Japanese, French, German, Russian, and Spanish. Manuals remain in English; some technical explanations may also remain in English. - **Model Scope**: Consult the documented assumptions, units, and model limits when interpreting results. The plane-wave animation explains a principle and is not a general-purpose, time-resolved physical simulation.
