Figure | Working principle of thermoradiative signatureless communication. Thermoradiative signatureless communication achieves covert transmission of data by rapidly modulating mid-infrared photodiodes, balancing forward and reverse bias luminescence. Only fast detectors resolve the signal; slow observers observe no evidence of communication.
