Radiation Pressure induced Nonlinearity in Micro-droplet
… such a high Q factor, the WGM can exert strong radiation pressure on the droplet interface, push it outward, increase the length of optical path, and produce a red-shift in WGM resonance. Our experimental results have found that the ratio of those resonance shifts and the optical power coupled …

Radiation pressure effects in a suspended Fabry-Perot cavity
We report on experimental observation of radiation-pressure induced effects in a high-power optical cavity. These effects play an important role in next generation gravitational wave detectors, as well as quantum non-demolition devices. We describe two experiments in which a low-transmission input …

Highly Physical Solar Radiation Pressure Modeling During Penumbra Transitions
Solar radiation pressure (SRP) is one of the major non-gravitational forces acting on spacecraft. Acceleration by radiation pressure depends on the radiation flux; on spacecraft shape, attitude, and mass; and on the optical properties of the spacecraft surfaces. Precise modeling of SRP is needed …

Quantum noise and radiation pressure effects in high power optical interferometers
… of the optomechanical coupling between radiation pressure and mirror motion. A computational tool is developed to model complex optomechanical systems in which these effects arise. The simulation tool is used to design an apparatus capable of demonstrating a variety of radiation pressure …

Solar radiation pressure, drag and gravitational effects on a dust particle in Earth orbit
… perturbations on particle orbits is the solar radiation pressure (SRP), which is defined as the pressure exerted by the photons constituting the light from the Sun. Colombo et. al studied the orbital dynamics of ``smart-dust'' under the effects of SRP and atmospheric drag. The numerical model …

Computationally Efficient Optimization of Formation Flying Trajectories, with Solar Radiation Pressure, near Lagrange Points
… may be modeled under the influence of solar radiation pressure (SRP), which expands the domain of fuel-free trajectories it can exploit by treating SRP as a means of actuation rather than a perturbation to be corrected. Since the restricted three-body problem has no closed-form solutions, …

Stability of Beams, Plates and Membranes due to Subsonic Aerodynamic Flows and Solar Radiation Pressure
… due to subsonic aerodynamic flows or solar radiation forces. Beams, plates and membranes are simple structures that may act as building blocks for more complex systems. In this dissertation we explore the stability of these simple structures so that one can predict instabilities in more …

Optimal state estimation for the optimal control of far-field acoustic radiation pressure from submerged plates
Sound pressure radiating from vibrating structures submerged in fluid, as in the case of a vibrating panel in a submarine hull, is usually undesirable. An optimal control methodology for the suppression of far-field acoustic radiation pressure from submerged structures has been developed by …

Significance of Specific Force Models in Two Applications: Solar Sails to Sun-Earth L4/L5 and GRAIL Data Analysis Suggesting Lava Tubes and Buried Craters on the Moon
… However, non-gravitational forces, such as solar radiation pressure (SRP), can significantly influence the motion of a spacecraft. Incorporating SRP within the dynamical model can assist in estimating the trajectory of a spacecraft with greater precision, in particular, for a spacecraft with a …
