Cosine harmonics
WebNov 6, 2024 · See here for an example of how to compute spherical harmonics on the 2D grid (theta, phi), and plot the results as a nice surface in 3D. By the way, you will want to compute the surface values over the full range of angle [0,pi] and [0,2*pi], so that your surface does not have a hole at the south pole or a gap along the prime meridian. WebBelow the complex spherical harmonics are represented on 2D plots with the azimuthal angle, , on the horizontal axis and the polar angle, , on the vertical axis. The saturation of the color at any point represents the magnitude of the spherical harmonic and the hue represents the phase.

WebA harmonic wave is a general term for a wave which, at some instant of time, can be described by a sinusoidal function ( i.e. it is a sine or a cosine function). They are the simplest of waves to consider, and we will devote this chapter to exploring their properties. 7.1 Transverse sine and cosine waves
