Without any index matching, there is a limit on the range of both beam position and angle for which the light beam of a given diameter and shape can be coupled in and out of the anterior chamber of the eye.
Utilizing this general expression, the arch shape can be easily formulated for a beam subjected to various types of loadings, such as uniform loaded beams or eccentrically loaded columns, on condition that an appropriate α is known.
Similarly, nanowires' shape can be used to produce narrow-beam lasers or light-emitting diodes (LEDs), Gradečak says.
Although the reflector shape can be obtained with high surface accuracy by these methods, its beam pointing accuracy cannot be easily guaranteed, even for circularly polarized feeds.
First, diffuse beam shape can no longer be analyzed using DFTs, as heterogeneities would affect the Fourier spectrum.
In the framework of the generalized Lorenz-Mie theory, the beam shape coefficients can be primarily determined by means of finite series or using quadratures.
The numerical simulation results indicate that, the dark hollow intensity distribution of the output shaped beam can be maintained well for a certain propagation distance during which the dark region will not decrease whereas the ideal hollow Gaussian beam will do.
By designing the phase modulation profile, which loaded into the LC-SLM carefully, the experimental results indicate that the dark hollow intensity distribution of the output shaped beam can be maintained well even at a distance much more than 550 mm from the LC-SLM, which agree with the numerical simulation results.
Since there are many control points (each individual antenna element) in a phased-array, the radiated beam can be shaped to give a desired pattern to the beam.
Numerical experiments demonstrate that the natural frequencies and mode shapes of the beam can be actively altered using the piezoelectric bonded actuators.
