Abstract: The radio waves commonly used in terrestrial wireless communication are severely absorbed by the conductive seawater. However, the low-frequency magnetic fields can penetrate a much farther ...
Abstract: A four-channel mode division multiplexing (MDM) transmitter is demonstrated with $4 \times 80$ Gbps signaling, assisted with a low-loss two-dimensional grating coupler over $1.85 ~\text{mm}^ ...
