About this app

EMCCalculator is a pocket toolkit for EMC engineers, hardware designers, and RF test technicians. Estimate key quantities on the bench or in the chamber—no account and no network required—with formulas shown for every result.

EIGHT CORE MODULES
• Electric field strength (V/d or from radiated power)
• Magnetic field strength (wire current or E/Z₀)
• Radiated power (from E and distance, or I²R)
• Shielding effectiveness (measured ratio or material/frequency model)
• Conducted interference (V=I·Z or √(P·Z))
• Radiated interference (far-field E vs. power and distance)
• Coupling (voltage or impedance methods, dB)
• Impedance matching (Z_match=√(Z₁·Z₂) or VSWR from Γ)

FEATURES
• Module grid home screen; responsive tablet layout
• Per-module inputs with SI units and range checks
• Calculate / clear; result card with value, formula, and notes
• Light & dark theme; portrait and landscape

Use for quick pre-compliance checks—not a substitute for accredited lab measurements or regulatory filings.
