Reverberation Benchmark problem

  

Figure 3: Transmission loss contours produced by RDOAST for Test case 3b of the Reverberation and scattering Workshop. a) Forward propagating field. b) Backscattered field

The following RDOAST data file represents the test case 3a from the NORDA Reverberation and Scattering Workshop. The resulting contour plots of the forward propagated and backscattered fields are shoown in Fig.3.
