Linköping University researchers achieve a tenfold performance boost in conductive polymer metasurfaces, advancing the field ...

To deal with the complicated non-convex optimization problem, an alternating optimization (AO)-based algorithm is adopted to decouple it into three subproblems which are further solved individually.

Then, to further reduce the computational complexity, the problem is reformulated as the difference of convex programming problems, which can be addressed by the concave-convex procedure. Numerical ...

Monofocal and multifocal lenses are both types of artificial intraocular lens (IOL). A monofocal lens has one focusing distance, whereas a multifocal lens can focus on close and far distances at ...
