Topology optimization of PIFA loaded with magnetic material by using FDTD method

In this study, we apply uniquely the topology optimization method to optimize the configuration and arrangement of the magnetic materials, which is inserted in the planar inverted F-antenna (PIFA) by using adjoint variable method (AVM) and the FDTD method. The aim of study is to confirm the validity of using topology optimization method for designing the configuration and arrangement of the magnetic materials.
