Compact wideband balun bandpass filter based on half‐mode corrugated slot

Electronics Letters, 2021
A design method of compact wideband balun bandpass filter (BPF) with high selectivity based on corrugated slot is proposed here. To realize wideband balun response in compact size, metal strips are deployed parallel to the half‐mode corrugated slot (HMCS)

Five‐way radial filtering power divider using back‐to‐back quarter‐mode substrate‐integrated waveguide and microstrip resonator

Electronics Letters, 2021
This paper proposes a five‐way filtering power divider (FPD) based on a back‐to‐back quarter‐mode substrate‐integrated waveguide (QMSIW) and microstrip resonator. The FPD is composed of two layers of the dielectric substrate.

Parasitic High Q-Factor Open-Box Modes With 3-D Printed Dielectric-Filled Metal Waveguides

IEEE Access, 2021
High Q-factor open-box mode resonances have been found in the microwave measurements of several 3-D printed dielectric-filled metal-pipe rectangular waveguides (MPRWGs).

PIN-PMN-PT Surface Planar Waveguides Realized via He⁺ Implantation. [PDF]

Nanophotonics
Helium‐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.

Characterization of contact properties at interface between metal and graphene up to 15 GHz

Engineering Reports, 2021
The contact properties between metal and monolayer chemical vapor deposition (CVD) graphene were investigated. Coplanar waveguides (CPWs) composed of CVD graphene‐based signal lines and Au‐based ground lines were fabricated.

Novel dual‐mode filters implemented by quarter mode folded substrate integrated waveguide

Electronics Letters, 2021
Two dual‐mode filters implemented by folded substrate integrated waveguide (FSIW) are proposed here. The high order modes (TE103 and TE301) in the FSIW cavity are employed to realize the function of filters. The non‐resonating node TE202 mode is employed
