Abstract: This paper developed a photonically actuated ultrawideband, two-dimensional transmit array using a Fourier optical lens as a beamformer. Data encoding was developed, in which custom IF ...

Abstract: To improve the estimation accuracy of two-dimensional (2D) direction-of-arrival (DOA) of uniform rectangular array, and increase the degrees of freedom of the array, this paper proposes a ...

As populations age worldwide, the burden of valvular heart disease has grown exponentially, and so has the proportion of affected women. Although rheumatic valve disease is declining in high-income ...
