Well yes the geometry of the split rings is what causes the resonance, and ultimately the negative permeability, but my question is what is in the wave-matter interaction that stops the propagation of the electromagnetic wave. Truly, as u stated, if you solve Maxwell's equations with a negative...
Thanks for that, although i had already come across that article i missed the most important sentence "If instead of electrons the material response were due to harmonically bound magnetic moments, then a negative magnetic response would exist."
Anyone find any other article that would expand...
Metamaterial structures such as split ring resonators exist such that at their resonant frequency, a stop band occurs, and are effectively therefore opaque to electromagnetic radiation at those frequencies. Could anyone explain this mechanism?
