Methods, systems, and devices for underwater communication are described. In some examples, a communication system may comprise a transmitter configured to excite surface electromagnetic waves along a water surface, utilizing the water surface as a superlens to focus the intensity of the excited surface electromagnetic waves from an object plane of the transmitter through the water surface. The transmitter may be further configured to communicatively couple with a receiver that may be configured to detect the surface electromagnetic waves propagated from the transmitter across the water surface. Some implementations enable efficient underwater radio communication and imaging over significant distances, leveraging the superlensing effect of surface electromagnetic waves for enhanced signal propagation and reception.

This invention relates to the field of underwater robot technology, specifically to an autonomous recovery method and system for underwater robots based on binocular vision and multi-source fusion. The system includes an AUV and a recovery platform. The AUV is equipped with a binocular camera, IMU, DVL, and USBL. The recovery platform is equipped with a guide light array, an auxiliary light source, a pressure sensor array, and a recovery cage. The method includes four stages: long-distance repositioning, high-precision visual guidance, multi-source fusion control in the visual failure zone, docking determination, and fixation. In the visual failure zone, the system activates the bottom auxiliary light source and constructs a multi-source fusion framework. It deeply fuses the two-dimensional deflection angle of the auxiliary vision, the high-frequency attitude of the IMU, the three-dimensional velocity of the DVL, and the absolute position of the USBL, and outputs the six-degree-of-freedom pose of the AUV in real time. This ensures end-effector attitude stability, improves system robustness and environmental adaptability, and solves the problems of not being able to provide complete attitude information and poor anti-disturbance capability in the near-range visual failure zone.
