Radar scattering from a turbine’s moving blades can interfere with Doppler radar systems, producing ghost images. Understanding the scattering properties of a blade helps to mitigate any potential issues. This study compares the radar cross section of a metal turbine blade, a hollow fiberglass turbine blade, and a hollow fiberglass turbine blade with a metal spar using XFdtd.
The use of general purpose computing on a GPU is an effective way to accelerate the FDTD method. This paper introduces ﬂexibility to the theoretically best available approach and examines the performance on both Tesla and Fermi architecture GPUs and identiﬁes the best way to determine the GPU parameters for the proposed method.
This application note from the January 2013 issue of Microwave Journal demonstrates the process of adding an electrically steerable, conformal antenna array to the body of a high speed missile. By leveraging XF’s XStream GPU Acceleration, a complex 3D simulation including multiple array elements with curved surfaces that could take several hours was completed within a few minutes.
In this paper, a conformal 2D FDFD Eigen mode method is derived for solving arbitrarily shaped waveguides or transmission lines. Some examples such as horn antennas, circular waveguide filters and differential pairs are presented to show the capabilities of the developed conformal 2D FDFD Eigen mode solver.
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.
Array modeling is a multistep process that often includes several revisions until the design goal is met. The Mobile Base Station Designer in XF’s XTend Script Library helps to speed up this design process. XStreamGPU Acceleration rapidly simulates the array using the actual antenna model to ensure the final design meets the design criteria. This presentation demonstrates how to design a conformal antenna array on a curved surface.
KEC, a UK manufacturer of EMC interconnect components and cable harness assemblies, strengthened its market leadership and differentiated itself from the competition by offering a unique technology. Using Remcom’s XFdtd to model and simulate customers’ designs, KEC can identify problems early in the process and recommend corrections before the EMC certification stage. This enables customers to avoid costly mistakes and pass certification testing on the first try.
When ReGear Life Sciences developed a new therapeutic deep heating garment for the shoulder, they needed to validate that the SAR value complied with all applicable FDA and FCC safety regulations before releasing the product to the market. Remcom performed EM simulations, made recommendations on a safer design, and provided the documentation necessary for ReGear to get approval for the product.
