Evanescent Fields Inside a Cut-off Waveguide as Near Fields
نویسندگان
چکیده
Usually, electromagnetic evanescent waves are some kinds of near fields. However, it looks as if the evanescent waves inside a cut-off waveguide had nothing to do with any near field. In this paper, we will show that the evanescent waves inside a cut-off waveguide can also be regarded as the near fields of an aerial array.

Dual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications
A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
متن کاملDirect and Inverse Medium Scattering in a 3d Homogeneous Planar Waveguide
Time-harmonic acoustic waves in an ocean of finite height are modeled by the Helmholtz equation inside a layer with suitable boundary conditions. Scattering in this geometry features phenomena unknown in free space: resonances might occur at special frequencies and wave fields consist of partly evanescent modes. Inverse scattering in waveguides hence needs to cope with energy loss and limited a...
متن کاملPhoton Localization inside a Waveguide Modeled by Uncertainty Principle
In the present work, an attempt is made to understand electromagnetic field confinement in a subwavelength waveguide structure using concepts of quantum mechanics. Evanescent field in the waveguide is looked as inability of the photon to get confined in the waveguide core and uncertainty of position is assigned to it. The momentum uncertainty is calculated from position uncertainty. Schrödinger...

A wide variety of optoelectronic devices with novel gratings are being created for which knowledge of the internal optical fields and details of loss mechanisms are highly desirable. To this end, we have built apparatus and developed techniques for simultaneous measurement of the scattered and evanescent fields in the near field of the active region of grating-type waveguide devices combined wi...
متن کاملEfficient coupling into slow light photonic crystal waveguide without transition region: role of evanescent modes.
We show that efficient coupling between fast and slow photonic crystal waveguide modes is possible, provided that there exist strong evanescent modes to match the waveguide fields across the interface. Evanescent modes are required when the propagating modes have substantially different modal fields, which occurs, for example, when coupling an index-guided mode and a gap-guided mode.
