Abstract
A navigation-communication-integrated metamaterial sonar for underwater vehicles is provided, and belongs to the field of ocean detection and communication. The metamaterial sonar is a metamaterial composite structure including a group of disc array with the same diameters, a disc backboard and water gaps. By adjusting the period p of the disc array, a board thickness t1 of each disc, the thickness g of each water gap, the radius wof the disc array, the radius wand the thickness tof the backboard, the working states of underwater navigation and underwater acoustic communication may be flexibly switched by changing working frequencies, and the navigation-communication-integrated sonar may be realized.
