This paper introduces XFdtd’s transient EM/circuit co-simulation capability, which combines the strength of 3D full-wave electromagnetic simulation with the flexibility of circuit solvers.
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.
Electromagnetic simulation has been used by RF engineers for many years to aid the design of automotive radar sensors, but the increasing demands of advanced driver assistance systems (ADAS) are changing the methods used. This paper introduces FDTD’s advantages for automotive radar circuit and systems level designers, including simulation of very large problems, more efficient memory requirements, and the ability to reveal sources of coupling.
This whitepaper demonstrates how XFdtd's time-domain approach enables rapid development by allowing engineers to determine the performance of a fully detailed sensor model installed behind a piece of fascia without needing to build prototypes and run tests in an anechoic chamber. The analysis of a 25 GHz sensor frames the discussion.
This presentation demonstrates how the 3D ray tracing code in Wireless InSite can accurately predict received power coverage even in a multi-room environment containing many walls and different materials types. In order to verify the accuracy of the code, the floor plan of Remcom’s business offices was modeled in the software with a WiFi antenna and a third party tool was used to create a coverage plot of the received power throughout several of the suites.
Wind turbines located near a radar installation can significantly interfere with the ability of the radar to operate properly. Remcom has performed a number of research efforts into the impact that wind turbines and wind farms have on radar returns for Air Traffic Control (ATC) radar, early warning radar, weather radar, and instrumentation radar. Highlights of some of these effects and relevant samples and white papers are provided in this brief overview.
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.
Wind turbines located near radar installations can significantly interfere with a radar’s ability to detect its intended targets. Remcom’s XGtd software is a high frequency solver capable of calculating the radar cross section of electrically large objects. In this paper, interference from wind turbines is predicted using XGtd simulations.
