Substrate-Integrated Rectangular Waveguide Bandpass Filters [PDF]
, 2007 本篇論文採用兩種不同的方法在印刷電路板中構成垂直金屬壁，來形成基板合成波導帶通濾波器，實作了數種單層基板合成矩形波導帶通濾波器的架構，並實現在Ro4003上。 首先用Ro4003印刷電路板製作三階帶通濾波器，並以K反轉器的方式設計，其中的共振器用二分之一波長導波管，等效導波管的垂直金屬壁是用銀膠來實現，為了量測，在其兩旁作了一個轉接電路，轉接到50歐姆微帶線。 另一種設計為矩形波導共振腔的垂直金屬壁是以金屬連通柱列來等效，共振腔用類似共平面波導(CPW)的槽線激發，將饋入電路與輸入 ...

Modal Expansion Analysis of T-Shaped Waveguide
IEEE Access, 2019 The T-shaped waveguide (T-waveguide for short) is a new kind of wideband waveguide which is easier to fabricate than conventional wideband waveguides. This paper presents the modal expansion analysis of the T-waveguide.

Attenuation in corrugated rectangular waveguide
Electronics Letters, 1971 The attenuation characteristics of two corrugated rectangular waveguides propagating the dominant hybrid mode are shown to be significantly better over a wide bandwidth than those for a plain guide propagating the TE10 mode.

Efficient First‐Principles Inverse Design of Nanolasers
Laser &Photonics Reviews, EarlyView.This article introduces a first‐principles inverse‐design framework for nanolasers that directly incorporates nonlinear lasing physics. By unifying steady‐state ab‐initio laser theory (SALT) with topology optimization, it reveals how spatial hole burning, gain saturation, and cavity‐emitter coupling shape laser performance, enabling efficient discovery

Non‐Uniform Programmable Photonic Waveguide Meshes
Laser &Photonics Reviews, EarlyView.Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

A new rectangular waveguide to coplanar waveguide transition [PDF]
, 1990 A new rectangular waveguide to coplanar waveguide (CPW) transition is described. The transition uses a ridge in one of the broad walls of the waveguide and a nonradiating slot in the opposite wall to split and rotate the electromagnetic fields of the ...
