This paper derives an analytical solution to convert sound field representation from the angular spectrum to the circular harmonics expansion. A sound field is decomposed to plane waves by the spatial Fourier transform and represented by the angular spectrum. A plane wave is also described by the circular harmonics expansion. In the proposed formulation… (More)
