Surface waves on a pair of parallel undirectionally conducting screens

Studies on planar helical slow-wave structures for traveling-wave tube applications

“…The planar helix structure studied in [16]- [23] is infinite in width along the ydirection. To confine the planar helix structure in the transverse direction, it was suggested in [21] that for one of the modes, the edges of the UC screens can be connected.…”

“…A pair of unidirectionally conducting (UC) screens has been proposed and studied in some detail in the past [16]- [20], [22]- [23]. Besides that, the two screens have current flow in directions oblique to the direction of wave propagation.…”

“…Dielectric slab solutions can be decomposed into transverse symmetric (even) and transverse antisymmetric (odd) cases [16], meaning E x , E y , H x and H y are symmetric or antisymmetric, respectively, with respect to the x-axis.…”

“…Fig. 3.2 (b) have been derived in[16] in a manner similar to that described in Section 2.2.4. Choosing the transverse anti-symmetric mode, the characteristic equation is…”
