Systematic Topological Design of Metamaterials: Scalar and Vectorial 3D Metamaterials and their Realisation

Dr. Michael Zedler

The Edward S. Rogers Sr. Department of Electrical and Computer Engineering (Electromagnetics)


Metamaterials are compound materials exhibiting electromagnetic properties not readily found in nature. Novel antennas, couplers, imaging systems and methods for the reduction of the radar cross-section based on these properties have been proposed in literature.  In this talk a systematic synthesis technique for metamaterials is presented. The foundation of this approach is that metamaterials consist of unit cells that are small compared to the wavelength. The topology of the unit cell's network representation can be derived from space-discretising schemes in 1D, 2D, and 3D.  Using this technique two novel isotropic 3D metamaterials are synthesised. Maximally-symmetric and planar physical realisations are proposed and verified by full-wave simulation and experiment, respectively.


Dr.-Ing. Michael Zedler received the Dipl.-Ing. degree from RWTH Aachen University of Technology, Germany. His Master thesis title is"Fabrication and time-domain characterisation of photonic crystals in the THz frequency range" which was supervised by Prof. Kurz and Prof. Haring-Bolívar. The Dr.-Ing. degree he received from Munich University of Technology, Germany, is for his thesis "Systematic Topological Design of Metamaterials: Scalar and Vectorial Metamaterials and their Realisation" which was supervised by Prof. Russer. It can be found online here. In Oct. 2008 he joined the group of Prof. Eleftheriades in Toronto as a PostDoc. His research interests include chip-integrated antenna design, periodic structures and metamaterials.
