Unlike existing methods results are produced in a very wide range of frequencies and source semi-angles with controllable precision. For this reason closed-form expressions are used to describe the truncation errors of all integrals and infinite sums involved. Impedance values of increased accuracy are also provided in tabulated form for engineering use and a new radiation mass-load model is derived for low-frequencies.}, type={Article}, title={Radiation Impedance for Square Piston Sources on Infinite Circular Cylindrical Baffles}, URL={http://czasopisma.pan.pl/Content/118243/PDF/aoa.2020.135254.pdf}, doi={10.24425/aoa.2020.135254}, keywords={cylindrical baffle, radiation impedance, radiation mass-load, piston source}, }
