Scalable Plasma Force Field Systems for Kinetic Projectile Defense: Physical Modeling, Material Requirements, and Economic Feasibility

This paper presents a comprehensive analysis of plasma force field technology (plasma window systems) adapted for kinetic projectile defense across multiple scales: personal (1-2m), vehicle (5-10m), building (50-100m), and city (1-10km). We model the physics of plasma-based force fields and electromagnetic deflection systems, calculate energy requirements, analyze metamaterial and magic angle enhancement opportunities, and provide cost estimates for each scale. Our analysis shows that while personal and vehicle-scale force field systems are achievable with current technology at costs of $50K-500K, building and city-scale implementations face significant energy challenges requiring 10-100 MW continuous power and capital costs exceeding $100M-10B. We identify critical research directions including moiré metamaterial plasma confinement, pulsed operation modes, and hybrid mechanical-plasma force field systems.
