electrodynamics

name	electrodynamics
description	Electrodynamics reasoning and knowledge graph — extends landau-graph with boundary-value methods, waveguides, antennas, scattering, crystal optics, coherence theory, and nonlinear/strong-field electrodynamics from 6 standard textbooks.
unit_system	SI
unit_note	All formulas in this skill use SI units, following Jackson and Griffiths. Maxwell: ∇·E=ρ/ε₀, ∇×B=μ₀J+μ₀ε₀∂E/∂t. Coulomb: F=q₁q₂/(4πε₀r²). Lorentz force: F=q(E+v×B). ε₀ and μ₀ appear throughout. Landau-graph (which this skill extends) uses GAUSSIAN units. For conversion, load the `si-gaussian-conversion` skill.

Electrodynamics Skill Graph

Extends landau-graph with applied electrodynamics, optics, and strong-field phenomena. All edges point FROM landau-graph TO this skill; landau-graph is never modified.

Graph Structure

• Reasoning nodes: Boundary-value methods, waveguide modes, antenna radiation, scattering cross sections, optical coherence, nonlinear response
• Knowledge nodes: Concrete EM phenomena — method of images, Mie scattering, Fabry-Perot, birefringence, SHG, pair production, etc.
• Edges: Connects to landau-graph reasoning nodes (prerequisite, reasoning-instance, analogy). No reverse edges.
