Cascaded domain engineering optical phased array for 2D beam steering
Nanophotonics, 2023 The current approach to 2D optical phased array (OPA) encounters challenges, such as the requirement for a highly tunable laser that is incompatible with certain 2D beam-steering applications or significant power consumption, large antenna spacing and ...

On state-space elastostatics within a plane stress sectorial domain: the wedge and the curved beam
, 2008 The plane stress sectorial domain is analysed according to a state-space formulation of the linear theory of elasticity. When loading is applied to the straight radial edges (flanks), with the circular arcs free of traction, one has the curved beam; when

Vibration of a Laminated Beam with a Delamination Including Contact Effects
Shock and Vibration, 2004 Certain results are presented in this paper on damped vibration of a laminated cantilever beam with a single closing delamination. In order to investigate this task the finite element method has been applied in the current study.

Coherent amplitude modulation of electron-beam-driven Langmuir waves [PDF]
Annales Geophysicae, 2013 A linear approach to the phenomenon of irregular amplitude modulation of beam-driven Langmuir waves, developed in a previous paper, is extended to explain periodic modulation as well.

In-domain damping assignment of a Timoshenko-beam using state feedback boundary control
, 2022 International audienceIn this paper, we combine the backstepping methodology and the port Hamiltonian framework to design a boundary full state feedback that modifies the closed-loop in-domain damping of a Timoshenko beam. The beam under consideration is

Concurrent Multi-Beam Digital Predistortion Using FFT Beamforming and Virtual Arrays
SensorsA digital predistortion (DPD) scheme for concurrent multi-beam transmission in fully digital multiple-input, multiple-output (MIMO) systems, using Fast Fourier Transform (FFT) beamforming and so-called virtual-array processing, is proposed.

DIMENSIONAL REDUCTION FOR THE BEAM IN ELASTICITY ON AN UNBOUNDED DOMAIN
Mathematical Models and Methods in Applied Sciences, 1999 The dimensional reduction method is investigated for solving boundary value problems of the beam in elasticity on domain Ωd:=ℝ×(-d,d) by replacing the problems with systems of equations in ℝ. The basic tool to analyze the dimensional reduction technique for problems in an unbounded domain Ωd is using of Fourier transformation.

Embedded homogeneity of beams in the nonlinear domain
International Journal of Solids and Structures, 2015 Abstract The notion of embedded homogeneity of thin-walled structures is introduced as the property characterizing the provenance of such a structure from a homogeneous material. This property needs to be distinguished from other definitions of homogeneity formulated exclusively in terms of a purely structural constitutive equation.
