Angular distribution of scattered pressure of plane wave from simulation results and theoretical solutions versus \(ka\) (\(f = 235\;{\text{kHz,}}\) \(850\;{\text{kHz,}}\) \(1109\;{\text{kHz,}}\) and \(2348\;{\text{kHz}}\)) incident pressure amplitude is one, plane wave width is 2.8 mm, and cylinder radius is 2 mm): a \(ka = 0.5\), b \(ka = 1.8\), c \(ka = 3.0\), and d \(ka = 5.0\). The arrows represent the plane wave direction
