EMI shielding for the electromagnetically contested decade.
5G mid-band and millimetre-wave deployment, defence AESA substrate isolation, and the connected-device build-out all depend on broadband EMI attenuation that holds through 16 GHz. GTX precision nickel mesh delivers 65–75 dB across the full band — independently validated at IIT Delhi.
USD 9.8 B TAM 2030. Attenuation physics does not forgive commodity materials.
The combination of dense 5G mid-band infrastructure, accelerated Ka-band defence communications, and hundreds of millions of connected edge devices has pushed the EMI-attenuation burden into frequency territory where commodity copper and aluminium mesh fall off. The market opportunity for high-attenuation precision mesh is neither speculative nor distant — it is specified into every major infrastructure tender being written in 2026.

Physics, not marketing.
EMI attenuation falls with frequency in all woven-mesh materials. The rate at which it falls depends on wire purity (eddy-current behaviour), wire diameter (skin-depth interaction), and weave geometry (aperture size relative to wavelength). NP1 ultra-pure nickel, drawn to 0.025 mm, woven to 200–400 mesh, sits in the geometry envelope that holds 65+ dB attenuation all the way to 16 GHz.
The commercial implication: a single mesh specification can cover the 5G mid-band (sub-6 GHz), the upper-5G / Wi-Fi-6E band (6 GHz), satellite downlinks (C, X, Ku bands), and early Ka-band defence communications — eliminating the multi-material stack that would otherwise be required.
