Document Type and Number:
WIPO Patent Application WO/2024/082778
Kind Code:
A1
Abstract:
The present invention relates to the field of microwave circuit and antenna optimization. Disclosed is a parameter-topology hybrid optimization method for electromagnetic device design. In the method, an adjoint sensitivity analysis method is used to simultaneously solve gradient information of structural parameter variables and material density variables, thereby achieving gradient optimization of the device structure and topological shape, and the method has the characteristics of high convergence rate and high optimization efficiency; the topological shape in an optimization area is characterized by the pixel material density, the correlation between the material density variable and the finite element mesh is reduced, and thus, finite element meshes having different precision can be used at different stages of the optimization process, to balance the optimization efficiency and the calculation accuracy. Compared with a conventional material distribution method, pixel density values are used as topological optimization variables, the optimized structure has smooth boundaries, thereby reducing errors during processing.
