CNT Nanocomposite EMI Shielding — Reflection & Absorption Loss (2D)

This is the 2D counterpart to the 3D CNT-EMI-shielding scene, computing the identical percolation and shielding-effectiveness physics through three flat plots instead of a rendered field. A Balberg excluded-volume percolation model turns CNT loading and aspect ratio into a network conductivity, visualised as a grid of CNT dots whose connecting edges switch on once the volume fraction clears the percolation threshold. A Schelkunoff plane-wave model then 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, shown as a wave lane where the incident field partly reflects and the rest decays exponentially through the panel. A third panel sweeps shielding effectiveness across the whole frequency range so you can see the reflection/absorption trade-off directly, while the side panel tracks σ_eff, skin depth δ, SE_R, SE_A and the total shielding effectiveness in decibels live.
