Rapid antenna design optimization using shape-preserving response prediction
An approach to rapid optimization of antennas using the shape-preserving response-prediction (SPRP) technique and coarsediscretization electromagnetic (EM) simulations (as a low-fidelity model) is presented. SPRP allows us to estimate the response of the high-fidelity EM antenna model, e.g., its reflection coefficient versus frequency, using the properly selected set of so-called characteristic...
متن کاملDerivative-Free Design Optimization of Sonnet-Simulated Structures Using Shape-Preserving Response Prediction and Space Mapping
A two-level derivative-free algorithm for design optimization of structures simulated using Sonnet em is introduced. The presented technique exploits a coarse-discretization model of the structure of interest that is optimized on a coarse grid using pattern search. Space mapping optimization is subsequently performed with the underlying surrogate model created using limited amount of coarse-dis...
متن کاملA topology-preserving level set method for shape optimization
The classical level set method, which represents the boundary of the unknown geometry as the zero-level set of a function, has been shown to be very effective in solving shape optimization problems. The present work addresses the issue of using a level set representation when there are simple geometrical and topological constraints. We propose a logarithmic barrier penalty which acts to enforce...
متن کاملShape Design Optimization of Unimorph Piezoelectric Cantilever Energy Harvester
The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...
متن کاملThe Effects of Shape Parameterization on the Efficiency of Evolutionary Design Optimization for Viscous Transonic Airfoils
The effect of airfoil shape parameterization on optimum design and its influence on the convergence of the evolutionary optimization process is presented. Three popular airfoil parametric methods including PARSEC, Sobieczky and B-Spline (Bezier curve) are studied and their efficiency and results are compared with those of a new method. The new method takes into consideration the characteristics...
