where b n (kR) is the normalized far-field mode strength and depends on the sphere boundary [8], l = 1, 2, …, L, and d1 = 1, 2, …, D1.
where b n d 2 kR, k r d 2 is the normalized near-field mode strength and depends on the sphere boundary and the source distance r d 2. Similarly, aN l, d2, k) represents the transfer characteristics from the d2th near-field source to the l th sensor.
For a sphere of size equal to one-tenth of the electrode size, the values of the ER increments were found to be very low and to depend on the sphere position: 0.3% close to the edge of the electrode and 0.05% at its centre.
Such hierarchically structured hollow-sphere arrays have demonstrated a tunable optical transmission stop band in the visible-near-IR (Vis NIR) region from 455 to 1855 nm, depending on the hollow-sphere size and the fine structure [25].
A prominent feature of Pentacam is the improved map for ectasia detection analysis by Belin/Ambrosio; in order to calculate an elevation, a reference sphere (BFS) is used with a radius depending on the K. Next, the sphere (BFS) is optimised, excluding the central area of 4 mm, thus highlighting pathologies and facilitating the detection of subclinical keratoconus.
Sphere diameters: silica 10 μm, PS 12 μm, PMMA 8 μm; BR film thickness: 160 μm. Figure 5 also shows that sedimentation eventually ceased at a certain depth, depending on the type of sphere.
Crucially, each laser shines at a couple of distinctive wavelengths depending on the precise size of the sphere, as shown in the graph.
This point of view has been exploited in the proof of Theorem 3.1 where the idea is precisely to view the perimeter of E as an integral functional over the sphere depending on the function u and then to write the second order Taylor expansion of that functional.
Depending on the charge put to the spheres they show up black or white.
These colloidal crystals diffract light in the UV, visible and the near-infrared (NIR) spectral regions, depending on the size of the silica spheres and according to the Bragg's law.
