3.3.1. CircSrc_SWE.m¶
Calculate the sound pressure generated by a circular radiator using the spherical wave expansion (SWE) method.
The sound pressure is expressed as
(3.3.1)¶\[p_{n_i}^{m_i}(\mathbf{r})
=
4\pi
p_0
\sum_{\ell_i=0}^\infty
\mathcal{R}_{2\ell_i+|m_i|}(r)
Y_{2\ell_i+|m_i|}^{m_i}(\hat{\mathbf{r}})
Y_{2\ell_i+|m_i|}^{m_i}(\pi/2,0)\]
where \(\mathcal{R}_{2\ell_i+|m_i|}(r)\) is given by Eq. (3.3.2).
