摘要

对挡板圆形活塞辐射的研究通常从瑞利积分开始。本文通过求解无限大圆柱波导中挡板圆活塞的亥姆霍兹方程，提供了瑞利积分的另一种推导方法。虽然瑞利积分通常被解释为简单源的和，但本文的推导表明，瑞利积分也可以被解释为贝塞尔光束的和。采用替代公式计算了带挡板的圆活塞辐射的轴向压力，并对涡旋光束的亥姆霍兹方程进行了数值求解。

An alternative approach to modeling radiation from baffled circular pistons (L).

The study of radiation from baffled circular pistons often begins with the Rayleigh integral. The present letter offers an alternative derivation of the Rayleigh integral by solving the Helmholtz equation for a baffled circular piston in an infinitely large cylindrical waveguide. While the Rayleigh integral is typically interpreted as a sum of simple sources, the present derivation shows that the Rayleigh integral can also be cast as a sum of Bessel beams. The alternative formulation is used to recover the axial pressure radiated by a baffled circular piston and solve the Helmholtz equation numerically for a vortex beam.
