Methodsofsimulation ofthegutter-type helical system

Homogeneous andinhomogeneous gutter-type helical slow-wave systems areconsidered. Modelsofthe systemsareproposed. Characteristics ofthesystems, calculated usingthecommercial software packageCST Microwave Studio andthemulti-conductor lines method, arepresented. Properties andadvantages ofthegutter-type systems arerevealed.
