In this experiment, two 4K movies (The Wandering Earth and Titanic) are transmitted via the two subdiffraction-limit channels. a Test scenario schematic of the line-of-sight real-time transmission, where the wireless signal emitted by the transmitter goes through the barrier and is received by the receiver. Photographs of the test scenario of receiver (b) and transmitter (c). d Frames of the two original movies to be transmitted. The same frames as decoded by the receiver after being transmitted by the SPP-based system (e) and by the microstrip system (f)
