Abstract
A quasi-static method for solution of the electromagnetic problem of waves in a uniform helix made of an infinitely thin perfectly conducting tape that can be used for the analysis of the helix eigenmodes in a broad range of the structure parameters is proposed. The electromagnetic problem is reduced to a system of integral equations for longitudinal components of electric and magnetic currents. The system of integral equations is solved in the static approximation by the method of Schwinger transforms. Explicit forms of functions describing electric and magnetic currents are found. A variational solution to the electromagnetic problem is obtained. The results of the numerical analysis of the eigenmodes of a tape helix are presented.
