Optical phased arrays borrow concepts from radar phased array science and technology to provide non-mechanical beam steering of electromagnetic radiation in the far field. Like radar phased arrays, this is achieved through controlling the relative ph

During superior solar conjunction of a spacecraft, the spacecraft has limited communication with the ground station due to the effect of the Sun on RF signal transmission. Our analysis of data that has been obtained during several MESSENGER (MErcury

During the superior solar conjunction of spacecraft, the spacecraft have a very limited communication with the ground station due to the effects of the Sun on the RF signal transmission. Our analyses of data received during a recent solar conjunction

We simulate the propagation of both a partially spatially coherent infra-red (IR) and a visible laser beam through a turbulent atmosphere, and we compare the intensity fluctuations produced in the simulation to the intensity fluctuations that are obs

Optical beam spread and beam quality factor in the presence of both quartic phase aberrations and atmospheric turbulence is numerically analyzed. We obtain analytical expressions for both the mean-square beam radius and the beam quality factor using

Optical beam spread and beam quality factor in the presence of both an initial quartic phase aberration and atmospheric turbulence are studied. We obtain the analytical expressions for both beam radius-squared and the beam quality factor using the mo
