We present a simulation
and experimental study of silver meshes
to determine their performance for transparent electromagnetic interference
(EMI) shielding. Simulations were employed to study the effects of
the silver mesh’s width, pitch, and thickness on EMI shielding
efficiency (SE) in the 8–18 GHz frequency range and transparency
in the visible spectrum. We demonstrate a scalable, facile fabrication
method that involves embedding meshes in glass by etching trenches
in glass and filling and curing reactive particle-free silver ink
in these trenches. Our silver meshes achieve 58.4 dB EMI SE with 83%
visible light transmission and 48.3 dB EMI SE with 90.3% visible transmission.
The combination of high-conductivity silver, small widths (1.3 to
5 μm), and large thicknesses (0.5 to 2.0 μm) enables the
best performance of metal meshes as well as single-sided shielding
materials for transparent EMI shielding, as reported in the literature.
