Webb8 dec. 2024 · The CGH that is responsible for each individual beam is calculated by using the holographic beam shaping technique, afterwards all the CGHs are multiplexed and encoded into one phase-only hologram by adding respective linear phase grating such that different curves are appeared in different positions of the focal regions. WebbA 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 is significantly reduced. To solve the constructed array optimization problem, a fast descent search algorithm is provided, where the convergence is proven … Webbso-called shaped-beam emission patterns that cover their service areas.
