Linear embedding via Green's operators (LeGo)
Wireless communication systems will have to improve in the future to meet ever increasing demand. The design of these systems requires the use of simulation methods. The performance of existing simulation methods is not good enough for design purposes. We are developing a simulation method for design applications for next generation communication systems (5G/6G). This simulation method is based on LEGO (Linear Embedding via Green鈥檚 Operators), which is an in-house developed integral equation domain decomposition technique. An example of a 5G/6G design application is an antenna array system.
Within the (Innovative Systems and Automated Design for 5G/6G Connectivity and Radar applications) project, Eindhoven University of Technology is focused on the research and development of next generation communication systems (5G/6G). In the EMPMC lab we focus on electromagnetic simulation methods for system-design flow within InnoStar.
A LEGO [1] solver will be used for the simulation of antenna arrays. Each antenna element is placed inside a subdomain (LEGO brick). The field interactions are modelled via equivalent currents on the brick boundaries. A scattering operator (S) is computed that gives the relation between equivalent incident currents and equivalent scattered currents on a brick boundary. The relation between incident and scattered equivalent currents between different bricks is given by transfer operators (T). The system is solved for the equivalent scattered currents over the brick boundaries.
