Summary:
The purpose of this study is to validate the Kirchhoff-Huygens equation and explore its directivity variation using the FDTD method. The equation simplifies the diffraction pattern calculations for aperture size, shape, and frequency changes. Previous studies focused on optics with sharp directivity, leaving its validity unverified for radio frequencies. A multiple screen diffraction model has been proposed as an alternative, aiming for faster computations in large domains compared to the computationally expensive mesh-division numerical method.
