Abstract : Iden ifiers: Birefringent delay lines. The ferrite birefringent-mode delay techniques resulted in the most compact and most lossy delay lines to date at X-band frequencies. The main obstacles are the nonlinear los characteristics with respect to input power an , apparently, the dielectric and magnetic losses of the ferrite materials that were ev luated. The main dvan ge are the large delays available ease of fabrication of the relatively simple geometry, and ease of control by means of an applied magnetic field. The most favorable geometry for the high-epsilo l y lines was the shielded helical transmission line operating in the O-th order of slow-wave mode. This line resulted in the best delay-to-loss ratios in the S-b1 frequency range. (Author)
