yeah.. they are independent, but i hope they arent always. coz in some cases, they are dependent... space time coordinates as they call, when an object or something is a function of time and space, then to find the solution, since it becomes complex, they revert to dependence on a single variable, keeping the other constant, for simple cases

A fast Fourier transform (FFT) is an efficient algorithm to compute the discrete Fourier transform (DFT) and its inverse. FFTs are of great importance to a wide variety of applications, from digital signal processing and solving partial differential equations to algorithms for quick multiplication of large integers.

Essentially all of electromagnetics is described by Maxwell's equations. An interesting feature of these partial differential equations is that there is no fundamental size scale. This leads to some very useful scaling properties. If you have an antenna design that works at frequency f1, but you need it to work at f2, you (...)
