Output probability spectra \({P}_{\kappa }(\vec{k})\) for various spatial frequencies κ. Plots at lower part indicate azimuthal spectral distribution P(φ) at radius k in, sector of input frequency and residual sector are normalized individually. Red dashed lines mark \({\vec{k}}_{{\rm{CBS}}}=-{\vec{k}}_{{\rm{in}}}\), sector of input frequency left open.
