✦ Synopsis

Fock scattering functions are necessarily used in the solution of cur¨ed surface diffraction problems faced by terrestrial communication system designers. These functions must be interpolated when their arguments are between y3 and 2. In the con¨entional method, a two-point Lagrange formula is used for interpolation, and 51 complex coefficients are needed. In this study, it is shown that Fock scattering functions can be e¨aluated by using the minimum property of Chebyshep olynomials. In this approach, only 20 complex coefficients are enough. This method is found to be less memory demanding, less time consuming, and consequently more efficient than Lagrange interpolation.
