12.10. Radiation from an oscillating concave dome in an infinite baffle

A concave dome [5] of radius a and radius of curvature R in an infinite baffle is shown in Fig. 12.30. In this problem, we shall introduce the concept of coupling whereby the field p ˜ I ( r , θ ) image inside the imaginary sphere, which includes the space inside the dome, is coupled to an external field p ˜ ( r , θ ) image . Again, the baffle can be removed so that we have an equivalent field which is symmetrical either side of the plane of the baffle. ...
