Abstract: Abstract An efficient finite-difference frequency-domain modeling of seismic wave propagation relies on the discrete schemes and appropriate solving methods. The average-derivative optimal scheme for the scalar wave modeling is advantageous in terms of the storage… read more here.

DOI: 10.1109/tap.2024.3410519
Abstract: A localized solution-based iterative solver for method of moments (MoM) analysis of large antenna arrays with disjoint, nonidentical elements is presented. The formulation introduces computational cost reducing extensions for the direct coupling technique (DCT), which… read more here.
