A discrete-time signal is a sequence of numbers defined only at integer values of time. Addition combines two signals sample by sample. y[n] = x₁[n] + x₂[n] Used in mixing and superposition of signals ...

Abstract: Electrically-large slot structures are common in building facades which are of great interest in scattering modeling for remote sensing and wireless communication applications. Existing ...

Abstract: In this contribution, the Ewald method has efficiently been applied to accelerate the computation of the rectangular waveguide Green’s functions (GFs) derivatives. Based on previous works, ...

These codes are pretty old. I no longer have MATLAB so I'm setting the repository to archive. These are functions I wrote during my post doc at USC (2009-2011) to work with receiver function data. It ...
