Abstract: In this letter, we introduce a novel sparse array (SA) architecture consisting of five uniform linear arrays (ULAs), referred to as the enhanced multi-ULA SA (EMUSA). A closed-form ...

Implement efficient Hamiltonian matrix construction leveraging momentum conservation to create block-diagonal sparse matrices, enabling larger system sizes through reduced memory footprint and ...

Abstract: In this paper, we investigate a near-field wideband multiuser communication system based on the symmetric nested array (SNA), which is formed by nesting a dense subarray within a uniformly ...

The assembly of elemental matrices is a critical step in FEM, allowing the construction of global system equations from the individual properties of each element. This project focuses on the indexing ...
