The radiation from an electric dipole antenna located on the axis of a prolate spheroid made of DNG metamaterial is considered. An exact solution to the problem is obtained. The far field and the limiting cases of a very thin spheroid and of a sphere are discussed in detail.
The directivity of vector sensors installed in the sonar dome of underwater vehicles will be distorted by vector sensors' baffle. This paper selects the soft prolate spheroid as the baffle model. The prolate spheroid baffle is meshed by finite element software, then the mesh is imported into the boundary element software and the directivity of pressure and vibration velocity of diffraction acoustic...
