Infinite-dimensional integrated digital image correlation (IDIC)
Background Digital image correlation (DIC) methods are common in laboratory experi­ments. Often termed two-dimensional digital image correlation (2D-DIC), the method uses a camera to acquire images of a planar object that is deforming nominally within the specimen surface plane that is being imaged. DIC algorithms typically perform the image registration...

Breaking temporal symmetries
Background A major challenge in telecommunications is placing antennas in a highly dense environment. Since typical non-magnetic radiators or scatterers obey reciprocity and have time symmetric responses, radiation patterns of an antenna in transmit and receive modes are identical. Because of this, densely placed antennas are prone to receiving echoes...
