What are non-reciprocal bandpass filters?

Question

I am not an electrical engineer. I have come to know about a term called as "Non-reciprocal Bandpass filters" which seems to be useful to me.
Here are some links to the papers (unfortunately there is no proper citation to find definition of the term)

I would like to know if they are nothing but a type of isolator. Are these devices discussed in any book?

According to this patent application:

A nonreciprocal bandpass filter is one that only allows
electromagnetic waves (signals) to flow in one direction.

It seems to be a way to eliminate circulators or other expensive devices in order to reduce the effect of reflections on a driving circuit.
