Calculation and analysis of the model of electromagnetic interference on printed circuit board traces

In this paper, we use the Constant-transform method to get the solution of the nonhomogeneous linear differential equations from Taylor model for a two-wire line in frequency domain. The solutions for the load current and voltage are equal to the results of the BLT equations. We give an analytic solution to the load voltage in response to an electromagnetic interference on two parallel striplines, and get the incident direction and polarized direction in which the electromagnetic wave dont cause interference voltage on the load of the two parallel striplines.
