Discretizing the Currents
Discretizing the object or solution space is commonly referred to as meshing. It is a necessary step to solve the integral equations.

Figure 1. The arbitrary shaped conducting body meshed into triangles.
The equation for the discretized currents can then be substituted into the EFIE (Equation 1) to yield:
In Equation 2, the current coefficients represented by are the only unknown quantity.
Before proceeding to the next step, it is necessary to take a closer look at basis functions.
