| Research Abstract |
This research constructed a new topology optimization that considers the change of electromagnetic properties due to the mechanical deformations for the structural designs of the high performance electromagnetic devices that use the change of permittivity of higher dielectric elastomers. That is, we, first, constructed the level set-based topology optimization method considering the geometrically nonlinearity based on the particle method that can evaluate the structural deformations of the elastomers. Next, the numerical method for analyzing the electromagnetic properties of the elastomers was developed using the finite element method. Finally, we tried to construct the topology optimization for the designs of electromagnetic devices that use the change of permittivity due to the structural deformations by combining the above two methods to take into account the coupled effects between the structural problems and electromagnetic wave propagation problems.
