Super-resolution imaging in multi-broadband of a ten-fold Penrose-type phononic quasi-crystal flat lens
A ten-fold Penrose-type phononic quasi-crystal (PQC) flat lens is constructed in water by steel rods. Super-resolution imaging in multi-broadband of the lens is realized. Results show that there are broad imaging bands on both sides of phononic band gaps (PBGs). In most imaging bands, there are freq...
