Magnetoplasmonic keychains for multiplexed polarization-encoded tags
This paper introduces a magnetoplasmonic keychain system that utilizes programmable plasmonic nanostructures to convert complex magnetic field configurations into unique, polarization-encoded optical signatures, creating a physically enforced encryption framework with a vast encoding space that is infeasible to decode without the specific magnetic key.
