我们在石英衬底上测量并模拟了高达1thz的平面狗包线（PGL）。pgl是单带传输线。证明了标准共面波导（CPW）和PGL之间的高效平面跃迁，并采用时域电吸收采样法测量了反射和透射波形。演示了皮秒脉冲的传输。对于4.2 mm长5 mm宽的条带和背靠背拓扑中的两次转换，我们在200 GHz附近获得了5 dB的损耗，在500 GHz附近获得了12 dB的损耗。200 GHz的值也通过频域测量得到了证实。
We present measurements and electromagnetic simulations of planar Goubau lines (PGL) on quartz substrate up to 1 THz. PGLs are single strip transmission lines. A very high-efficiency planar transition between a standard coplanar waveguide (CPW) and PGL is demonstrated A time-domain electroabsorption sampling method is used to measure the reflected and transmitted waveforms. Transmission of picosecond pulses is demonstrated. We obtain 5 dB of losses around 200 GHz and 12 dB around 500 GHz for a 4.2 mm-long 5 mum-wide strip and two transitions in a back to back topology. The value at 200 GHz is also confirmed with a frequency-domain measurement.
