WebSep 7, 2024 · The Method of Cylindrical Shells Again, we are working with a solid of revolution. As before, we define a region R, bounded above by the graph of a function y = f(x), below by the x-axis, and on the left and right by the lines x = a and x = b, respectively, as shown in Figure 6.3.1a. WebThe mode of a single-mode fiber normally has a shape which is similar to that of a Gaussian. In other cases, it is often convenient to decompose all the propagating light into different modes. That decomposition means …

A two-dimensional elastic membrane under tension can support transverse vibrations. The properties of an idealized drumhead can be modeled by the vibrations of a circular membrane of uniform thickness, attached to a rigid frame. Due to the phenomenon of resonance, at certain vibration frequencies, its resonant frequencies, the membrane can store vibrational energy, the surface moving in a characteristic pattern of standing waves. This is called a normal mode. A me…
