Numerical study of beam shape adaptation by anisotropic disk covering transducer or metamaterial

Metamaterials are intensely explored for their capabilities to modify sound beams. In addition frequency filtering, acoustic lenses offer intriguing possibilities shaping For the time being, versatility of metamaterials remains limitless. beam-shape adaptation, however, complexity suggests that manufacturers transducers could benefit from combining with more conventional materials. This paper investigates transmission a circumscribed beam through stratum anisotropic material examine change in shape after transmission. The incident is presumed originate transducer, possibly coated metamaterial field, before being transmitted layer. Different shapes, such as conical-like, Gaussian, and pillar beams, investigated. While results not exhaustive, they demonstrate shape’s adaptability.
