Abstract:

The near field pressure and the radiation impedance for an infinite phased array of circular pistons with the same velocity magnitude in a rigid plane baffle are calculated. A slowly convergent infinite series expression for the pressure, obtained from the appropriate Greens function, is transformed by the use of the Poissons sum formula into a more rapidly convergent infinite series expression. Numerical results are presented. A rough estimate of the location and value of the maximum pressure in the near field is obtained under certain restrictions. The radiation impedance of a piston in the infinite array agrees well with the average radiation impedance of a piston in a large finite array. Author
