Reply To: Electrostatic simulations of a modulator

One example of a symmetric distribution of the electric field can be found in this paper.

 The paper's image can be seen below. The paper considers a situation when two gold electrodes are placed on a lithium niobate substrate. As you see from the image below, the distribution of the absolute value of the electric field is symmetric with respect to x.

 

However, in my simulation, I obtain an asymmetric distribution of the electric field. Why would that be the case?

To clarify, in my simulation, lithium niobate is modeled as a semiconductor.

 

Thanks!
