Term: In electromagnetism, a meta material (or metamaterial) is an object that gains its (electromagnetic) material proper­ties from its structure rather than inheriting them directly from the materials it is composed of. This term is particularly used when the resulting properties have not been found for naturally formed sub­stances.

Metamaterials are often made up of a collection of objects whose separation is much less than the wavelength. At micro­wave frequencies often periodical arrays of current-conducting elements (such as loops of wire) are employed.

Research: Although the theoretical and practical aspects of microwave meta­materials are extensively discussed nowadays, the benefit of applying these ideas to microwave devices and systems has not been comprehensively demonstrated. With the focus on the DNG (double negative) material approach, we want to address in our work three major items: The development of 2D and 3D microwave metamaterials realisation schemes, the expansion of device performance by applying this approaches and the derivation of new operation principles. Within this background our group is working on various devices for the microwave regime:

  • SRR embedded in Microstrip environment
  • Leaky Wave antennas
  • Metamaterial Sensors
  • Compact Devices:
    • Antennas
    • Phaseshifter
    • Waveguides
