If the detector readings are proportional to the amplitude of the microwave e field, the data from the first polarization experiment should be proportional to cos(θ) where θ is the angle between transmitter and detector. if the readings are proportional to the energy stored in the e field, the readings should be proportional to cos2(θ). based on your data, are the detector readings proportional to amplitude, energy, or neither?

Fields and variables are proportional

Explanation:

To solve the problem we must first identify the Vector Intensity,

The intensity is given by:

We also know that the change given by the Intensity is always the square of the amplitude,

This is,

The intensity is proportional to the change exerted on

That is to say that in turn the amplitus is proportional to the Intensity.

On the other hand, relating the two variables we have

In this way we can conclude that the electric field of intensity is also proportional to
