Rectangular waveguide to circular waveguide mode converter is a critical components of a high-power microwave test system. In certain frequency band, the traditional method of round — rectangular waveguide mode converter can't satisfy the performance requirements. In order to solve this problem, this paper puts forward a kind of compact structure, and it has the characteristic of small reflection...
A terahertz (THZ) cross-guide waveguide directional coupler with high directivity is realized in this paper. This construction covers the frequency from 205 to 235 GHz. Its coupling value is 20±0.8 dB, and the isolation is greater than 51 dB, which means that the directivity is in excess of 30 dB.

A new sampling path of discrete complex image method (DCIM) is proposed to capture the information of the branch point accurately. The new path comprises of three segments. All these segments are very close to the branch point and the second segment will go through it directly. Along this path the information of the branch point can be captured very accurately. In the situation when the lateral wave...
