Second year PGR James Capers recently gave an oral presentation at General Assembly and Scientific Symposium
(GASS) of the International Union of Radio Science (URSI). Held only every 3 years, URSI GASS is one of the largest conferences about the theory of electromagnetism and radio science, attracting some of the biggest names in the field of Metamaterials such as Federico Capasso and Andrea Alù.
James says of the experience:
This was a very exciting opportunity to learn about the latest progress in Metamaterials research and to present my own work to the community. My presentation was about my work developing methods for “Designing Metamaterials to manipulate antenna radiation”. In my talk I presented a new method for designing Metasurfaces built from passive dipolar scattering elements. Our proposed method is fast, simple and efficient with the additional benefit of including all of the multiple-scattering effects in the system. I showed that our method can engineer several properties of antenna radiation; from improving efficiency to designing the exact far-field radiation pattern. This method may be used to design Metasurfaces that can meet the increasing demands placed on antenna systems due to the miniaturisation of technology, the upwards push in communications frequencies and the specific beam shapes required for sensing applications, for example on self-driving cars.
