使用现场计算程序MAFIA对柔性波导系统进行了模拟，首次实现了频率高达150 GHz的柔性波导系统，并在两种应用中运行。柔性波导系统由聚乙烯制成的矩形介电纤维与优化的锥形和波导适配器相结合组成，这使得柔性波导易于与传统波导结合使用。在140 GHz时最小衰减为4 dB/m；的测量值，比在相同频率下工作的d波段波导的测量衰减值小约6 dB。此外，还测量了不同弯曲半径下柔性波导的相移以及不同锥形光纤终端对柔性波导相移的影响。
A flexible waveguide system has been simulated using the field calculation program MAFIA, for the first time realised for frequencies up to 150 GHz and operated in two applications. The flexible waveguide system consists of a rectangular, dielectric fibre made of polyethylene combined with optimised tapers and waveguide adapters, which makes the flexible waveguide easy to use in combination with conventional waveguides. A minimum attenuation of 4 dB/m at 140 GHz; has been obtained with the dielectric waveguides, which is about 6 dB less than the measured attenuation of D-band waveguides operated at the same frequency. Additionally the phase shift of the flexible waveguides for different bending radii as well as the influence of different tapered fibre terminations was measured and is reported.
