FIBER OPTICS - University of Sydney School of Physics
www.physics.usyd.edu.auA step-index fiber is a cylindrical dielectric waveguide specified by its core and cladding refractive indices, ~zr and n2, and the radii a and b (see Fig. 8.0-l). Examples of standard core and cladding diameters 2a/2b are S/125, 50/125, 62.5/125, 85/125, 100/140 (units of pm).

www.qsl.net• Waveguide - Uses air as transmission medium and side walls of tube as return path. - Won’t support energy propagation below cutoff frequency. - Works best at ultra high frequencies with millimeter wavelengths. - With an air dielectric, signals propagate at the speed of light. - Very low loss due to smooth side walls and the air dielectric.
Bound States in the Continuum - Massachusetts Institute of ...
www.mit.eduThe waveguide supports a continuum of waves propagating in x that are either even or odd under mirror reflection in y; the odd ones (shown in orange) require at least one oscillation in y and only exist above a cutoff frequency (πc s/h), where c s is the sound speed and h is the width of waveguide. Since the plate respects the
