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)
Abstract:
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.
Biography:
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.
