This paper presents a new electromagnetic simulator called HOBBIES (Higher Order Basis Based Integral Equation Solver). HOBBIES is based on a parallel In-Core and Out-of-Core integral-equation solver and a personal pre- and post-processor called GiD®. HOBBIES presents some important features such as multiplatform and multilanguage environment, definition of models using symbolic variables, automatic...
The NEWUOA is a newly developed trust region based derivative-free method for solving unconstrained optimization problems. We present in this paper this powerful tool for antenna optimization. Two antenna design examples are optimized using simplex method, conjugate gradient method and the NEWUOA algorithm. Optimization results are presented and compared. The NEWUOA shows good performance and is proved...
