Abstract: The characteristic mode (CM)-based basis function method for connected array structures has been proven to be an efficient numerical approach. However, it generates a matrix equation for ...
👉 Learn how to show that two functions are inverses. The composition of two functions is using one function as the argument (input) of another function. In simple terms, the composition of two ...
Abstract: This paper investigates near-field extremely large-scale multiple-input multiple-output (XL-MIMO) systems with sparse uniform planar arrays (UPAs). Based on the Green’s function-based ...
