Far-field Approximation

Far-Field Approximation is an analytical method in electromagnetic theory that simplifies the mathematical representation of radiated fields at large distances from a source by neglecting higher-order terms, thereby enabling tractable computation of field behavior under the assumption of locally planar wavefronts.
