The gain computation for the traveling wave tube with dielectric-loaded rectangular waveguide grating; 介质加载矩形波导栅行波管的小信号增益计算 3. Under the assumption of the sheet-beam,the "hot" dispersion equation of the arbitrary groove rectangular waveguide grating traveling wave tube(TWT) loaded...
Namely, the open-ended rectangular waveguide is a very common technique in NDT due to its simple structure, ease of fabrication, and low costs28. The resolution of the rectangular waveguide probes is comparable to the larger dimension of the waveguide aperture. As a result, a large operative ...
Remarkable advancements have been made in the design of optical metasurfaces in recent years, particularly in compact designs. However, for their practical integration into diverse optical systems, there is a pressing need for metasurfaces to transition
A transfer matrix method is developed to calculate the electromagnetic field in a dielectric structure with circular cylindrical symmetry. The equations for the reflection and transmission coefficients of cylindrical waves from a single cylindrical boundary between two dielectrics and from a cylindrical multi...
We introduce and numerically validate the concept of few-layer bifunctional metasurfaces comprising two arrays of quasiplanar subwavelength resonators and a middle grid (array of rectangular holes) that offer both symmetric and asymmetric transmissions connected, respectively, with symmetric and asymmetric ...
Polarization response of artificially structured nano-antennas can be exploited to design innovative optical components, also dubbed “vectorial metasurfaces”, for the modulation of phase, amplitude, and polarization with subwavelength spatial resolution. Recent efforts in conceiving Jones matrix formalism ...
