 This paper proposes a new type of phononic crystal, PC, lens for broadband sub-wavelength imaging of flexural waves in plates. The proposed lens uses a square lattice design with square-shaped EFCs, enabling the group velocity vector to always be perpendicular to the lens interface regardless of the frequency and incidence angle. This results in a broadband imaging capability, allowing for sub-wavelength imaging over a significantly wider frequency range than previously possible. Numerical and experimental demonstrations show that the proposed lens has the potential to be used as a powerful tool for broadband sub-wavelength imaging applications.
