Wireless power transfer is an emerging technology used in many applications, including consumer electronics, electric vehicles, and biomedical implants, and will undoubtedly see continued growth over the next decade and beyond. This presentation demonstrates how XFdtd can be used to simulate and analyze wireless charging systems.
This presentation demonstrates a new multiphysics-based ESD analysis capability which allows the ESD testing process to be analyzed via computer simulation. This will save companies time and money by allowing ESD protection to be optimized during the design phase, thus reducing the number of prototypes required to be built and tested.
Full wave matching circuit optimization (FW-MCO) is a new technology that combines full wave, 3D EM simulation with circuit optimization into a novel approach for solving an age-old RF problem: determining which component values provide the desired match for a given matching network layout. This article describes the design process using the design of a matching circuit for a GPS-Bluetooth antenna.
XF’s Circuit Element Optimizer utilizes full wave analysis to select the component values for a given printed circuit board (PCB) layout. The tool allows design engineers to optimize matching circuit lumped element values directly in the EM layout where the coupling from multiple antennas and the ground return current paths are taken into account. This whitepaper gives an overview of how the Circuit Element Optimizer works and the benefits it provides.
The bottlenecks for simulation tools used for antenna design are typically in two areas: project setup and simulation speed. By reducing the time spent in these two areas, RF engineers have more time to design their antennas. Remcom’s XFdtd reduces these bottlenecks in several ways, including parameterization, scripting, advanced meshing techniques, and GPU implementation of the computational algorithm.
This paper presents a thorough investigation into the effects of several phone chassis-related parameters—length,width, thickness, and distance between the head and phone—on the bandwidth, efficiency, and specific absorption rate (SAR) characteristics of internal mobile phone antennas. The studied antenna-chassis combinations are located beside an anatomical head model in a position of actual handset use.
