Solver Performance of Accelerated MoM for Connected Arrays
Harald Hultin, Lucas à kerstedt, B. L. G. Jonsson
Simulating and developing large rectangularly shaped arrays with equidistant interspacing is challenging as the computational complexity grows quickly with array size. However, the…

An Array Decomposition Method for Finite Arrays with Electrically Connected Elements for fast Toeplitz Solvers
Lucas à kerstedt, Harald Hultin, B. L. G. Jonsson
A large part of the geometry of array antennas is often partially defined by finite translational symmetries. Applying the method of moments (MoM) with the RWG-like element on an a…

On Adaptive Frequency Sampling for Data-driven Model Order Reduction Applied to Antenna Responses
Lucas à kerstedt, Darwin Blanco, B. L. G. Jonsson
Frequency domain sweeps of array antennas are well-known to be time-intensive, and different surrogate models have been used to improve the performance. Data-driven model order red…
