An eigencurrent description of finite arrays of electromagnetically characterized elements
article
To describe the behavior of a finite array, the current distribution on each of its
elements is represented by a finite number of eigencurrents or modes. Subsequently, the
eigencurrents of the array are expanded in terms of these element eigencurrents. For
uniform linear arrays of loops and dipoles, the array-eigencurrent expansions and their
associated eigenvalues are investigated. We focus on their parameter independent and
diagonalizing features, and on their interpretation in terms of far-field characteristics and
(standing) wave behavior
