A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.230180, discusses orthogonal matrix of polarization combinations: concept and application to multichannel holographic ...

This letter studies the possibility of synthesizing an orthogonal beamforming network (BFN) with an arbitrary number of inputs and outputs and beam-shaping functions. The proposed synthesis approach ...

Description Sorry if this is a novice misunderstanding, but my understanding is that given a symmetric matrix, dsyev () should return in place the matrix of eigenvectors (when JOBZ = 'V'). The ...

Moreover, the evaluation of these contributions to the matrix elements is less straightforward than that in the orthogonal case. Following the outline of Löwdin (34) on how to calculate the ...

Compute matrix elements using the generalised nonorthogonal Wick's theorem. Here, the computation is divided into three objects: reference_state: Container to store the definition of reference ...

Received 25 July 2014; revised 25 August 2014; accepted 23 September 2014 ABSTRACT Given a symmetric matrix X, we consider the problem of finding a low-rank positive approximant of X. That is, a ...
