Abstract:

The combined techniques of chemical vapor deposition and photocopying offer the promise of new and useful slow-wave structures for microwave tubes. These slow-wave structures include conventional periodic structures such as the helix, meander line and interdigital line. In addition, structures based upon an anisotropic sheath are possible. These may be superior to single periodic structures in cases where a uniform dc boundary is desirable, or dielectric charging is a problem, or special control of spatial harmonics is desirable. Also, these are the types of structures that result if low loss bulk anisotropic materials are found. Author
