We present a new type of photonic structures in quadratic nonlinear materials that enable efficient and continuous all-optical deflection. The structures are based on two-dimensional modulation of the nonlinear coefficient and consist of a set of symmetric or anti-symmetric arcs that form a periodic pattern in the propagation direction and a chirped pattern in the transverse direction. Stoichio...

Controllable parafoil and payload aircraft are controlled with downward deflection of left and right parafoil brakes. Lateral control is obtained by differential deflection while longitudinal control is created by collective deflection of the left and right side parafoil brakes. The work reported considers an alternative method to control parafoil and payload air vehicles by tilting the parafoi...

This paper presents explicit analytical solutions of the pressure coefficient and the pressure ratio across the oblique shock and expansion waves in function of the flow deflection angle. These new explicit pressure-deflection solutions can be efficiently used in solving applied aerodynamic problems in supersonic flows, such as the aerodynamics of airfoils and wings in supersonic-hypersonic flo...

We propose two novel electro-optic (EO) deflectors based on two new nonrectangular geometries: the parabolic and the half-horn configurations. These devices not only provide excellent deflection angles, but also have the potential to build nonblocking 2 x 2 optical switches. A deflector figure of merit is defined, and comparisons with existing EO deflectors are given. Devices fabricated in LiTa...

Deflection profiles of y} and y are shown in Fig. 1 for M -100 kg, 7=490 kN, c = 307 m/sec, a = 226 m/sec, at t = 0.68, 1.02 ane 1.29 sec. At these times the mass positions are * = 52, 118, and 188 m. As shown in Fig. 1, maximum deflection is at the mass location. To determine the adequacy of the simplified mathematical model used in the analyses, the cable deflection at a known position was mo...

The steady state behavior of regular two-connected multihop networks in homogeneous load under hot-potato and single-buffer deflection routing is analyzed for ultrafast optical applications. Manhattan Street Network and ShuffleNet are compared in terms of throughput, delay and deflection probability both analytically and by simulation. It is analytically verified that single-buffer deflection r...

Microcantilever-based sensors can be used to detect molecular absorption of, for example, hydrogen gas, which causes changes in the surface stress, leading to deflection of the cantilever. Such a deflection can be determined by means of optical beam deflection, capacitance-, or piezo-resistance based readout. We have recently proposed a compact integrated mechano-optical sensor using a novel an...

The right-hand rules show the direction of the spin-induced deflection of baseball pitches: thus, they explain the movement of the fastball, curveball, slider and screwball. The direction of deflection is described by a pair of right-hand rules commonly used in science and engineering. Our new model for the magnitude of the lateral spin-induced deflection of the ball considers the orientation o...

We propose a dielectric photonic structure for ultrafast deflection and focusing of relativistic charged particle beams. The structure is designed to transform a free-space laser beam into a deflection force that acts on the free particles with the same optical phase over a distance of travel that is much greater than the laser wavelength. The proposed structure has a two-dimensional geometry a...

The adaptronic spindle for milling machines can be positioned by piezoelectric actuators in three axial directions. This enables an automatic online-compensation of tool deflections in the milling process. The tool deflection is calculated by the process forces and the tool stiffness previously measured. A new spindle position is calculated to counteract the tool deflection. This procedure can ...
