Research Topic Description, including Problem Statement:

Metamaterials have been widely used in the past few years for RF as well as acoustic shielding applications. These are typically only applicable over a limited bandwidth, and there has been limited research in the metamaterial absorber design for combined acoustic and RF application, from a few Hz up to 30 GHz. There are additional research gaps that RF absorption effects suffer from the incidence polarization of its signal, meaning that shielding often does not fulfill the requirements in the IC’s scenarios, as outlined in the last section. 

In this topic we would like to explore the research and development of novel lightweight metamaterial absorbers to provide the frequency absorption over a wideband range from a few Hz to 30 GHz that is insensitive to the incident signal phase. 

The development would help in providing an absorption and attenuation of various sound and RF signals emanating from multiple consumer devices and sources and bring new vitality into traditional approaches.

Example Approaches: 

  • Computational modelling and calculation of the architectural design.
  • Model and simulate the behavior of metamaterial absorber for its intended frequency range.
  • Identifying candidate materials and novel composite structures with negative permittivity and permeability, potentially using conductor and dielectric sandwich materials.
  • Optimize the design for the physical construction.
  • Experimental verification of the physical design and its analysis for its application.
  • Development of lightweight design for its integration within a physical space.
