A New Technique for Broadband Matching of Open-Ended Rectangular Waveguide Radiator [PDF]
Sensors, 2023 The maximum reflection at an open end of a standard rectangular waveguide is about −10 dB in its operating frequency range. It is often used without matching. For critical applications, it is desirable to further reduce the reflection coefficient.

PIN-PMN-PT Surface Planar Waveguides Realized via He<sup>+</sup> Implantation. [PDF]
NanophotonicsHelium‐ion implantation turns bulk PIN‐PMN‐PT relaxor ferroelectric crystals into high‐quality planar optical waveguides. The guiding surface layer retains its single crystallinity and large electro‐optic response without postimplantation annealing, whereas a buried damage layer acts as the optical barrier.

A Novel Method to Broaden the Single-Mode Bandwidth of the Rectangular Waveguide
International Journal of Antennas and Propagation, 2022 In this paper, a new class of broadband and low-loss transmission line called slotted rectangular waveguide (SRW) is proposed and analyzed. The proposed SRW consists of the rectangular waveguide and the inverted low-loss slotline, which can selectively ...
