For typical … WebThe sine of that acceptable angle (assuming an incident ray in air or vacuum) is called the numerical aperture, and it is essentially determined by the refractive index contrast between core and cladding of the fiber, assuming that the …
WebSimple, closed-form, approximate solutions have been found to describe the following properties of the guide: number of modes, their field configurations and propagation constants, numerical aperture, requirements for single-mode operation, field penetration in the slab, tolerance to curvature of the guide axis, dispersion, and impulse response. Web: An infinite array model is developed, which shows that there are only minor differences between the pattern of an element in a dielectric clad cylindrical array and that of an element in the corresponding planar array. This result suggests that the coverage of a finite dimension array over a cylinder of large radius can be evaluated with good …
