    摘要： Lossy slabs (46) are provided in linear-beam tubes such as coupled-cavity traveling wave tubes or klystrons to produce a more level tube response over its full operating band, and to eliminate oscillations at the upper cut-off frequency in the TWTs. The slab thicknesses are selected to produce a substantially non-resonant field of about one-quarter wavelength within the slab (46) when the tube is operated within its passband. The slabs (46) are arranged within openings of a tube structure (36, 42) and are formed from a dielectric material having a conductive mixture of at least about 15%.
