Investigation of the ribbed coaxial line with azimuthally non-regular screen

Models of the cylindrical electrode for physiotherapy formed by a ribbed coaxial line were investigated and analyzed in this paper. The increasing towered the open end one, two or three longitudinal slots in the screen electrode were used to achieve the required distribution of the electromagnetic field in the surrounding tissue. The averaged dispersion characteristics of the fabricated models were measured by a network-analyzer in the frequency band 100...3000 MHz. The obtained data had been compared with characteristics of the ribbed coaxial line in the absence of the slots.
