![]() ![]() One consequence of this scaling is that the amount of power in each mode can be different. ![]() The reason is because when the mode expansion monitor is calculating the modal fields of the structure, the mode amplitude is arbitrary and the fields are simply scaled such that the peak |E|^2 value is 1 with a phase of 0. Grating Coupler), or if you are expanding the fields using a different mode than what was injected by the source, the interpretation is less obvious. However, if you have multiple waveguide cross section geometries in the simulation (ex. What is mode expansion?Ĭonsider a waveguide/fiber that supports a set of forward-propagating modes, \( \varphi_ = 0 \), since there are no reflections in this setup. Note that if performing parameter extraction using FDTD, using ports and the S-parameter sweep tool is preferable since the port objects can act as both sources and monitors and return S-parameters as a result. ![]() See the Mode expansion monitor page for an overview of these objects and lists all input and output properties. This page provides additional information to allow users to get the most accurate results from their simulations. Screenshots Super Vectorizer Pro Merkmale und Beschreibung Hauptmerkmale: Neueste Version: 2.2. Mode expansion monitor simulation objects allow you to analyze the fraction of power transmitted into any mode(s) of a non-absorbing waveguide or fiber. Super Vectorizer 2 is a professional vector tracing software that automatically converts bitmap images like JPEG, GIF and PNG to clean, scalable vector graphic of Ai, SVG, DXF and PDF. ![]()
