Abstract:

Contents Poissons solution of the initial value problem Jordans lemma General formulas for the calculation of transient radiation Transient radiation from a piston membrane - work of Kozina and Makarov Transient response of a rigid piston in an infinite rigid baffle - work of miles Indicial impedance of a rigid piston in a rigid infinite baffle Transient radiation field of a vibrating plate edge clamped in a rigid wall Transient radiation from large aperture planar radiators - case of short waves Rectangular large aperture radiator illuminated by a step modulated sinusoidal signal Rectangular large aperture radiator illuminated by a rectangular pulse modulated sinusoidal signal Transient radiation from spheres The polynomials B sub n jkr sub o and its laplace inversions Transient radiation from spheres excited by arbitrary time signals Characteristic waves of exterior space Transient excitation of spheres by a sinusoidally modulated step function Ratio Rk of initial velocity potential amplitude of transient waves to the velocity potential amplitude of steady state waves in the far field Transient radiation from a spherical source of order n O for an impulse excitation Transient radiation from a spherical source of order n O for step sinusoid excitation Tail end of transient radiation from a spherical source of order n O Tail end of transient radiation from a spherical source of order n 1 Transient reaction of medium on a spherical radiator of order n 1 Theory of sound radiation from moving sources The transient field from an infinite line source of uniform strength Transient waves in two dimensions - work of barakat.
