摘要: A leaky-wave antenna for fluid environments includes a waveguide cavity defined by a waveguide wall. The waveguide cavity is filled with a waveguide fluid. The waveguide walls are made of either an anisotropic material that utilize one of orthotropic stiffness of the anisotropic material to control mode conversion, a band gap material to approximate an acoustically rigid boundary, and a combination of the two materials.
