Antennas and Computational Electromagnetism.

LINKS can count on more than 10 years of successful experience in project, experimental and numerical activities related to antennas, electromagnetic compatibility (EMC) and applied electromagnetism.

The group’s research has been a landmark for planning, prototyping and testing innovative antennas for years now, particularly for electronic scanning and low profile antennas, either conventional or metasurface paradigm-based.

Antenna design is supported by many internally developed state-of-the-art software tools, product of great experience in computational electromagnetism.

The group’s computational code and know-how are applied in commercially available SW and businesses can use them through professional consultation services and applied research projects partnerships (i.e. of the European Commission or of space agencies).

Computational expertise has given rise to independent tools that help the antenna engineering and development cycle, particularly in regard to fast qualification measurements and experimental diagnostics. The antennas software tool for diagnostics enables rebuilding the field on themselves (near field) starting from the one measured through conventional systems, and is present in a widely used market-available tool that can also couple measurements and simulations in the most widespread electromagnetic simulation commercial software.

The main electromagnetic simulation code developed by the team enables accurate (full wave) and reliable modelling of big structures with many geometrical details. The code can efficiently module structures with more than 100 wavelengths which scales comprehend many orders of magnitude, with details smaller that the wavelength. Hybrid methods enable even bigger dimensions by using high frequency approximation. More specifically, the group has developed and manages code for hypersonic-flying objects or vehicles analysis, both for prediction of RF communication channel (with blackout possibility) and for radar section prediction.

Another independent tool is a SW suite for automatic design of compact and reconfigurable antennas that uses the “direct design” concept, with no hypothesis or approximation on the radiation mechanism of the antenna.
Finally, the developed numeric tools have given rise to RF/microwave tomography code, both for medical applications and for non-invasive and non-destructive analysis of structures.
