Metamaterial Engineering

 
 
The extraordinary interest in electromagnetic Metamaterials is due to their unique capabilities to modify the propagation of the electromagnetic fields, which allows the design of innovative applications which were never before thought possible. Indeed, such "unique" features are at present being studied for the development of promising technologies with applications to several fields including public health, biomedicine, communications, security, aerospace, remote sensing, distributed monitoring, and public safety. Such applications, which cover the entire electromagnetic spectrum (from RF to optical wavelengths), include "perfect" imaging lenses with a negative index of refraction, cloaks of invisibility, miniaturized resonator antennas, thin frequency selective surfaces, as well as compact devices such as wave collimators, bends and rotators. However, it is well known that bandwidth and loss limitations represent an inherent drawback of many Metamaterial devices based on resonant structures. Accordingly, the availability of design techniques able to yield to Metamaterial-based broadband devices is of great interest from the scientific and industrial viewpoint.

Members of the ELEDIA Research Center are working on the development of several innovative devices based on metamaterials, including

  1. Multiband and wideband microstrip antennas exploiting Metamaterial substrates.
  2. Microwave and optical cloaking applications.
  3. Miniaturized field concentrators.
  4. Compact polarization rotators.
  5. Miniaturized beam splitters and collimators.
  6. Flat focusing lenses.

The research activities carried out in this area are specifically focused on the study, development, prototyping, and testing of innovative engineering applications based on the unique properties of electromagnetic Metamaterials with the purpose of bridging the gap between the already available theoretical results and the realization of reliable technologies.
