Abstract :
The computation of the total incident field distribution must include interactions between the different features that exist near the opening of the cavity. A UTD (uniform geometrical theory of diffraction) computer code can be used to compute the incoming field distribution at an aperture located at or near the opening of the cavity. This gives one the ability to place the open-ended cavity near other structures. The backscattered fields from an open-ended waveguide cavity attached to a flat plate were computed and measured at 10 GHz. Good agreement between the computed results and the measured ones is found.<>
