The Helmholtz equation … you are solving for steady state pressure at a single frequency. • Eigenfrequency : This will allow you to find the acoustic modes of a domain. These are frequencies and corresponding pressure fields where the Helmholtz equation and boundary conditions can be satisfied with no external drive

mhtlab.uwaterloo.caBessel’s differential equation, given as x 2 d2y dx2 +x dy dx +(x2 − ν)y =0 is often encountered when solving boundary value problems, such as separable solutions to Laplace’s equation or the Helmholtz equation, especially when working in cylindrical or spherical coordinates. The constant ν, determines the order of the Bessel functions ...

Helmholtz Equation - Northern Illinois University
nicadd.niu.eduP. Piot, PHYS 630 – Fall 2008 Summary • At z 0 –Beam radius is sqrt(2) the waist radius –On-axis intensity is 1/2 of intensity at waist location –The phase on beam axis is retarded by π/4 compared to a plane wave –The radius of curvature is the smallest. • Near beam waist –The beam may be approximated by a plane wave (phase ~kz).
