Electromagnetic Modelling and Circuit Integration

This research, using EM simulation tools, including some in-house software, focuses on design and modelling methodologies applied to circuit integration, with particular attention to layout and floor planning effects.

Electromagnetic simulation

Electromagnetic simulation concentrates on hybridization techniques to take into account structures of dissimilar scale. In particular, the TWF (transverse wave formulation) method, developed at ISAE and TLM (transmission line method), sharing the common strategy of formulating EM problems in terms of waves, demonstrate high hybridization capability and complementarity by combining their integral and differential attributes. Hybridization technique development is being carried out in cooperation with Munich TUM University and supported in part by the Centre de Coopération Universitaire Franco-Bavarois.

Methodology development

Methodology development for electromagnetic design and modelling aims to derive broadband models incorporating distributed and coupling effects, induced by design topologies including out-of-band behaviour.

Applications covered in these activities include electromagnetic modelling of opto-electronics and terahertz devices, carried out in cooperation with the other teams of the group. Terahertz propagation specificities, non-perfect boundary conditions and specific metal interactions, leading to significant changes in EM formulations and innovative 2D or 3D structures (for instance photonic band gap), thus revealing the high applicability of EM simulation.

This research also explores multi-physics applications resulting from system integration, such as fly-morphing on flexible substrates, developed in cooperation with DAEP. New developments are expected in electromagnetic formulations based on Lagrangian concepts.
