In order to study he endpoints’ response of printed-circuit-board（PCB） multi-conductor micro strips in the complex chamber electromagnetic environment

the Monte Carlo statistical methods were used to build reverberation chamber’s diffuse field. The agrawal coupling theory was used to calculate the equation of multi-conductor transmission lines

for the PCB multi-conductor transmission lines’ node responses simulation analysis. Then we verified the simulation results through experiments in a homemade experimental platform composed of the reverberation chamber

spectrum analyzer

power amplifier

current probes

photovoltaic equipment

etc. It is shown that the simulation agrees with the experiment results. The results show that the "full radiation electromagnetic environment" simulated by the Monte Carlo statistical methods agrees with the electromagnetic environment in reverberation chamber; the frequency that inductive current peak appears does not satisfy f=nc/2L（n=1

…; c denotes the transmission velocity

usually denotes the velocity of light; L denotes the length of transmission line）

and with the increasing of frequency

the amplitude of inductive current will attenuate; the change of the load will not affect the law of coupling curve

however

the amplitude of inductive current will decrease with the increase of load.
