The effective refractive index for the first-order reflection鈥搑efraction event (i.e., the case for the ray-transmission from air into a particle) has been previously derived by the authors. In this study, we further develop recurrence formulae for the effective refractive indices associated ...

The middle part of the core, being a region of lower refractive index, does not confine the power, and thus the power gets distributed over a larger area. This reduces the peak power in the core and increases the effective area of the fiber. Figure 2.22 shows the distribution of power ...
The obtained reflection (S11) and transmission (S21) coefficient results were employed to compute the effective medium parameters of the MSM structure, i.e., permeability (μ), permittivity (ε), refractive index (n), and impedance (z) values. The famous Robust method was adopted for this ...
Therefore, only the effective impedance can be affected, while the effective phase velocity or refractive index remains unchanged. If the frequency of a lowered effective impedance is selected to match the Fabry–Pérot resonance frequency of the equivalent system of effective impedance z, the wave ...
摘要: A method is given of calculating second-order singularities which are related to inflection points of slowness curves. An approximated formula is derived for the effective permittivity function in the neighbourhood of its singular points. A numerical analysis is presented of several piezoelectrics...
The guide walls are composed of surface reflective material with refractive index n = 1 − δ and decrement δ, where (224)θc=2δ. For 5-Å neutrons and a nickel mirror, the grazing critical angle for total reflection θs is 8.5 mrad, measured relative to the mirror surface. The ...
