In this paper, a checkerboard metasurface based on novel physical mechanism, optimized multielement phase cancellation, is proposed for greatly expanding the bandwidth of radar cross section (RCS) reduction. More basic metaparticles and, in particular, variable difference between them, increase ability to control electromagnetic waves. Interactions multiple local waves produced by at frequencies sampled superwide frequency band are manipulated and simultaneously achieve cancellation. The can...
Abstract Fourier ptychography (FP) is an enabling imaging technique that produces high‐resolution complex‐valued images with extended field coverages. However, when FP a phase object any specific spatial frequency, the captured contain only constant values, rendering recovery of corresponding linear ramp impossible. This challenge not unique to but also affects other common microscopy techniques — rather counterintuitive outcome given their widespread use in imaging. The underlying issue...
