The Photonic, Phononic and Meta- materials (PPM) group belongs to the Institute of Electronic Structure and Laser of the Foundation for Research and Technology, Hellas (FORTH). The research of the group concerns theoretical and experimental study of electromagnetic metamaterials and other photonic materials, such as photonic crystals and plasmonics, while there is a long experience also in the study of phononic (acoustic) crystals.

The main current research topics range between applied physics and electromagnetism to chemical synthesis of materials and structural characterization and instrumentation.


  • Electromagnetic wave propagation in composite media, with emphasis on metamaterials, photonic crystals, plasmonic structures, and random dielectric and metallodielectric systems.
  • Design, fabrication and characterization of left-handed metamaterials.
  • Design, simulation and experimental verification of both passive and dynamically controllable chiral metamaterials, as well as electromagnetic characterization of such metamaterials in microwaves and infra-red regime.
  • Realization/calculation of Casimir force between chiral metamaterials.
  • Synthesis and study of metal oxide thin films and nanostructures of (ZnO, InOx, WO3, TiO2, SiO2, VO2) emphasized in:
    (a) photocatalysis of organic pollutants in liquid and gas phase,
    (b) growth of novel metal oxide coatings with self-cleaning properties,
    (c) growth of thermochromic and electrochromic materials.
