Wave guiding properties of ribbed surface waveguides in three frequency domains
- 147 Downloads
A longitudinally structured surface waveguide is examined and the effect of the structuring on the wave guiding properties is explored. The waveguide structure is examined in three distinct wavelength regions and the results are discussed and compared. The Frequency domains are the microwave region around f = 400 MHz, the terahertz region around f = 400 GHz and the optical region around f = 400 THz. Special emphasis is placed on regarding the opposing behaviour of the wave attenuation versus the field extension.
