Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have a general question about material properties.

We know that the material property value depends on the input level. For example, the permittivity in a dielectric material changes depending on the applied electric field.

That being said, when we apply an alternating electric field, we receive a linear response while at the same time the electric field is going from 0 to the set amplitude. We go through a range of electric fields values before arriving at the final amplitude, yet we still receive a nice sine wave output which is indicative of a linear response.

This leads to the obvious conclusion that, for the "linear range" , we get a linear response depending on the amplitude of the input. At the moment, I cannot understand this. I would imagine the response would not be a clean sine wave (for a AC input) because the changing properties due to changing electric field.

Am I missing something here?
