Hello everyone,
First and foremost I would like to see if everyone's having a good day? (assuming you respond yes) Awsome! Secondly I was hoping someone would be able to help me understand how dielectrics work.
I don't need to know everything about dielectrics. I only need to know how they affect electromagnetic waves passing through them. More specifically how they would affect the amplitude of an RF signal having a frequency of anywhere between 10 MHz to 100 GHz and an unmodulated amplitude.
The reason I would like to know specifically about dielectrics is because I read the following from a patent description which can be found here http://www.freepatentsonline.com/5230029.html" :
"The results of non-normal plane-wave scattering from a planar three-layer guiding structure as illustrated in FIG. 1 in which the central dielectric film or layer is active are described." "A fine-grained scan of the plane-wave incidence angle, has revealed the existence of narrow discrete angles where large amplitude scattering resonance is obtained. Enhancements in the scattered field intensities on the order of 100 have been observed using active films 80 as thin as 6 microns."
From what I understand this means that this dielectric film 80 reflects an electromagnetic wave which scatters the amplitude of the incedent wave.
Ofcourse I could be terribly wrong seeing as how this is all very confusing to me, So if anyone out there knows what's really going, could you please either tell me "no, you're not right" or instead tell me "yes, you're correct" and then explain how the dielectric does this.
Sorry if this was all very confusing, but any help would be most appreciated.
