In recent years, superoscillations have become a new method for creating super-resolution imaging systems. The design of superoscillatory wavefronts and their corresponding lenses can, however, be a complicated process. In this study, we extend a recently developed method for designing complex superoscillatory filters to the creation of phase- and amplitude-only filters and compare their performance. These three types of filters can generate nearly identical superoscillatory fields at the image plane.
