Abstract: Sparse linear arrays (SLAs) are becoming increasingly popular due to their superior performance in achieving higher degrees of freedom (DOFs) compared to uniform linear arrays. However, most ...

Abstract: This study addresses leakage sources in plate structures by proposing a method for near-field and far-field recognition and full-field localization based on a linear piezoelectric sensor ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

Several approaches are capable of beating the classical 'diffraction limit'. In the optical domain, not only are superlenses a promising choice: concepts such as super-oscillations could provide ...
