1D photonic crystal

Chukwudi,

I encourage you to check out the webinars located at https://www.gotostage.com/channel/optiwave. I would specifically recommend the “Basic Examples & Analysis” as well as “Advanced Applications I”. These both provide a good starting point for learning to use the product.

Once you have reviewed those if you are still having issues you need to be more specific in what you are having issues with. What materials are you trying to load for example.

Chukwudi,

This is why I directed you to the “Basic Examples & Analysis” webinar as in that video I specifically show how to obtain the reflection spectrum from the power spectrum utility. I am not sure what version of the product you are using because there is no “spectrum analysis” tool in the existing product.

In the power spectrum tool, if you make sure the normalized box is checked then the results are normalized to the power and as such they vertical axis is a fraction of the input power.

It would indicate that there is more power than what is from the source. There are a few circumstances in which this can happen. One example I can think of is if you are using an observation point located at a focus. Another would be a poorly configured source.

Could you please attached the design in question so I can take a look?
