Slow surface magnetoplasmon in periodic semiconductor structure

Slow electromagnetic waves find numerous applications in a wide frequency range of the electromagnetic spectrum, from RF to the optical range. Now, surface plasmon polaritons studies are under way in thin semiconductor layers for active plasmonic circuits at THz frequencies [1]. Our work shows that the surface waves in periodic magnetoactive dielectric-semiconductor structure may have slowdown rate about 10³. A study of some other properties of this wave at submillimeter wavelengths was also made.
