Microwave Devices and Components
Remcom's XFdtd software is well-suited for any microwave device design or analysis task.
Whether the application is waveguides, power dividers, filters, couplers, or the like, XFdtd can provide quick, efficient, and accurate EM simulation results.
The Rotman Lens Designer (RLD) software output is compared to full wave results from XFdtd for a single lens design realized using different thicknesses of the same dielectric material to determine best design practices.
The Rotman Lens Designer (RLD) software output is compared to full wave results from XFdtd for a broad range of design frequencies to validate the performance of the software in different bands of operation.
The performance impact of the sidewall curvature of a Rotman Lens design is evaluated by comparison of several designs created in Rotman Lens Designer (RLD) with full-wave results simulated by XFdtd.
A microstrip gap waveguide containing a mushroom-type EBG surface is simulated in XFdtd and compared to measured results.
This paper demonstrates the design of Rotman lens for ESM sensor application in operation band 32-38 GHz. The initial design is created in Remcom’s Rotman Lens Designer and then verified against experimental measurements. Parameters of the realized prototype are presented and methods of increasing its performance are outlined.
Simulation can greatly enhance the design and prototype process when developing new products. This is especially true for the design of waveguide devices, such as a cavity filter, as the engineer can quickly calculate a number of key metrics leading to an optimal configuration. Through optimization via scripting, exceedingly fast processing using a GPU, and waveguide ports, this presentation demonstrates some of XF’s features for the design, optimization, and analysis of waveguide devices.
A brief overview of Remcom's Rotman Lens Designer.
In this paper, we present a design of wave ports including rectangular and circular waveguides, coax, microstrip and strip lines in XFdtd. We show the simulation results of some microwave circuit or antenna examples for validating the wave ports design.
In this video, a Remcom engineer walks through the steps to set up and tune a Ku Band microstrip lens in Rotman Lens Designer (RLD). Included is a discussion of the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script to automatically set up the ports and include the material properties.
This video is a tutorial that shows a rectangular waveguide being built using XF’s modeling techniques. You will learn how to use XF’s built-in materials library, create the waveguide interface, solve for and display lowest-order TE modes, and display the field results.
