Measurements of far-field profiles indicate a substantial beaming effect for CES LEDs, despite their few-micron-pitch pattern. Near-to-far-field transformation simulations and polarization analysis ...

And the far-field diffraction pattern with ten-fold rotation symmetry is generated due to the quasi-periodic array. The unit cells in the bottom right corner indicate the cyan thick rhomb and pink ...

A comprehensive study of the far-field diffraction pattern of Bragg reflection waveguides is presented. Using a Gaussian approximation of the near-field profile, an analytical formula for the ...

The diffraction from the small sample edges generates patterns in the far-field echoes which are determined by the mechanical properties of the sample. Without loss of generality, in this paper the ...

Nanoscale texturing, drilling, cutting and spatial sculpturing require not only high accuracy, but also the capability of manufacturing in the atmospheric environment. Towards this goal ...

Figure 3 shows the far-field patterns scattered by the rigid cone with the same geometrical parameters as in the previous case. Comparison of the curves in Figure 2 (a), Figure 2 (b) and Figure 3 (a), ...

Fresnel diffraction, or near-field diffraction, occurs when a wave passes via a small hole and diffracts, creating a diffraction pattern. The size of the pattern depends on the distance between a ...
