  • Considering EMC Radiated Immunity Testing Using Field Generators

    Many electronic products have the requirement of complying with electromagnetic compatibility (EMC) regulations, adding additional pressures to the process of bringing new products to market. These requirements have also made EMC testing much more important, driving additional needs for improving EMC test standards for new technologies and developing more efficient instrumentation for EMC testing. This article discusses the concept of applying EMC immunity testing with the use of field generators.

Why Engineering Simulation Is Critical To Success In Developing Autonomous Systems

An autonomous system’s contextual awareness and artificial intelligence software allows it to base decisions on sensor perception and the software’s mission objectives. Developing these systems raises new challenges that can only be met with the help of engineering simulation. Simulation enables thousands or even millions of operating scenarios and design parameters to be virtually tested with precision, speed, and cost economy.

Developing Efficient Design Procedures For Wideband, Low-Profile Antennas Using Altair FEKO

Low-profile, concealed antennas are often desired for diverse applications across many military and commercial vehicle platforms. Since antennas mounted close to the ground have decreased efficiency, potential antenna applications need to benefit from the coupling to the ground and/or rely on short distance communication. Traditional analytical propagation models are not applicable to short-distance near-ground signal propagation, so numerical modeling is required. FEKO electromagnetic simulation technology is an attractive solution with superior effect capabilities that account for mutual coupling between receiving and transmitting antennas.

Characterizing The Murchison Widefield Array Beam Pattern

The Murchison Widefield Array (MWA) radio telescope was constructed as a precursor to the Square Kilometer Array (SKA) at the Murchison Radio-astronomy Observatory in Western Australia. This case study focuses on this electronically steered phased array, where steering is achieved by introducing phase delays to each element in the array. The primary beam patterns in phased array antennas must be accurately known in order to correctly calibrate and image the data collected by the radio telescope.

Understanding RF Inductor Specifications

There are many key parameters that must be considered for RF inductor selection, including the mounting type, inductance value, current rating, DC resistance, self-resonant frequency, Q factor, and temperature rating. A balance must be met between the desired smaller sizes of the inductor package, and the inductance value and current rating. Once these two parameters are determined, the other parameters can then be optimized.

  • Video: Wind Turbines And Aircraft In The Presence Of Ground Clutter

    This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out. A basic filter has then been applied to remove the portions of returns with 0-Doppler (static clutter from the ground and wind turbine towers) to approximate what a radar might see after attempting to filter out objects not in motion. Although actual radars have much more sophisticated signal processing, this basic before/after animation of RCS from subsequent scans shows the problem that standard Doppler filtering would encounter when processing returns from a wind farm.

  • Video: Tuning A Microstrip Lens In Rotman Lens Designer (RLD) And Options For Importing To XFdtd

    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). We populate the physical, electrical, and transmission line properties and analyze the performance of the lens by plotting the array factor and beam to array phase error. This data helps us to further tune the lens by adjusting the focal ratio and beam port excitation, and then we export the S-Parameters. Finally, we discuss the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script. The script import method automatically sets up the ports and also includes the material properties.
