Effect of Ground Wind Shear on Aircraft Trailing Vortices

Abstract

and evaluated by substituting the -numerical values of transmittance reported by Edwards and Tdbin. Figure 2 presents the results for the apparent emittance of rectangular groove cavities with specularly reflecting metallic walls. Results for the case of dielectric walls can also be obtained in a similar manner. The effect of polarization is illustrated by the comparison in Fig. 2 between the present results and those of Sparrow and Jonsson who neglected polarization in their calculation. It is clearly indicated that the polarization effect is indeed significant in this case.
