Spectral properties of a periodic plasma waveguide

Periodic waveguides have numerous applications in modern microwave technology mostly due to their two fundamental properties: support of slow waves and existence of stop bands. These properties are common for a great number of waves in periodic media regardless of their nature. However, a reliable approach allowing an adequate analysis of the dispersion properties of the plasma waves in periodic plasma-filled waveguides is addressed for the first time.
