A new method for shaped-beam synthesis is proposed by taking the phases of the desired radiation field as design variables (notably not the usual element excitations). The number of design variables ...

Use Case / Problem Description The NVIDIA AI Blueprint for Video Search and Summarization addresses the challenge of efficiently analyzing and summarizing large volumes of video data. This can be used ...

In this paper, a firefly-cuckoo search algorithm (FCSA) is proposed to solve the beam pattern optimization problem of the random antenna arrays (RAA). FCSA introduces the Levy flight mechanism of the ...

Optical information security has become paramount in data-driven technological systems, where metasurface holography has emerged as a transformative paradigm for high-density optical encryption.
