CNT Nanocomposite EMI Shielding — Reflection & Absorption Loss

Aerospace composite skins carry embedded conductive layers — increasingly a percolating carbon-nanotube network instead of a heavier metal mesh — to shield avionics from electromagnetic interference and to dissipate lightning-strike current. This simulator ties the two physics together: a Balberg excluded-volume percolation model turns CNT loading and aspect ratio into a network conductivity, and a Schelkunoff plane-wave model turns that conductivity, the incident frequency and the panel thickness into a shielding effectiveness split between reflection loss at the surface and absorption loss across the thickness. A 3D field animation shows the incident wave arriving, part of it bouncing back as a reflected wave, and the rest decaying exponentially through the panel as skin depth and thickness compete — while the side panel tracks σ_eff, skin depth δ, SE_R, SE_A and the total shielding effectiveness in decibels live.
