摘要: The "flattened sheath helix" considered in this letter consists of a pair parallel unidirectionally conducting screens different directions and having dielectric media the sandwiched outer regions. Special cases are 1) normal flattened helix which inner medium is solid air, 2) inverted with two interchanged. guiding properties such structures studied.
