Near-field infrared spectroscopy simulations using Altair Feko

Radomes are used across multiple industries, including aerospace, defense, electronics, and telecommunications. When properly designed, the radome can actually enhance the performance of an antenna system. The proper selection of a radome for a given antenna can help improve the overall electromagnetic system performance by eliminating wind loading, allowing for all-weather operation, and providing shelter for installation and maintenance. Altair’s radome simulation solution helps to streamline the design of these complex components, ensuring performance while significantly reducing development time.

This white paper presents a study of wireless connectivity of electronic devices in the Wi-Fi band. For accuracy, the analysis will use the full polarimetric information for each device’s antenna pattern. The study focuses on wireless connectivity between lamps and light switches in an indoor environment, with the goal to set guidelines for spacing between transmitters and receivers: wall-mounted switch boxes and ceiling-mounted lamps, as well as pairs of lamps. In general, the work flow would be similar for any type of wireless connectivity in environments such as a smart home, an industrial site, as well as streets and intersections (vehicle-to-vehicle or vehicle-to-infrastructure communication).

Vehicle-to-vehicle (V2V) technology has the potential to significantly enhance driver safety. The type, placement, and orientation of V2V antennas all affect the performance of the communication system. Simulation software for high frequency electromagnetics can be used to analyze the farfield effects of various vehicle antenna configurations without the need to perform physical testing. We present a simulation-based method for optimizing the placement and orientation of a monopole antenna on a vehicle using a Global Response Surface Method (GRSM).

From the moment radar was first invented, it has proved its value in collision avoidance - first at sea, then in the air and later on the road. This white paper gives an overview of the development that has taken place.

Radar development was essentially motivated by military needs during the second world war, where radar use founded dozens of applications for instance navigation, aircraft location, enemy ship detection, anti-collision, and weather forecast.

Smart devices have touched and enhanced all aspects of our lives, from the way we conduct business to the way we relax at the end of the day. Designing antennas for wearble devices presents a unique set of challenges. In this technical article from Microwave Journal, these issues are discussed.

Bundles of electrical cables in vehicles, aircraft, ships and buildings pose electromagnetic compatibility and interference challenges to the electrical design engineer. Due to their lengths, they are more likely to radiate or pick up irradiation than many other electrical components and systems. Through several examples, this white paper will discuss how those challenges can be met with the aid of electromagnetic simulation.

At radar frequencies, 1GHz and above, asymptotic methods are usually preferred to calculate the radar cross section (RCS) of targets like aircraft, since the main parts of the target are more than an order of magnitude larger than the wavelength. The challenge is how to combine these methods to compute the RCS. In this white paper the two-step method that obtains accurate results in limited time is detailed.

Automotive radars are becoming standard equipment on vehicles. Their purpose is to adjust the distance between vehicles and/or alert the driver when dangerous situations arise. Several antenna architectures are used to cover the different safety functions in complex bumper/car chassis environment where the side effects become more and more significant on the radar performances. Hence, automotive radar integration process becomes a very important topic. Weak radar integration will generate gain loss, high side lobes levels and angular errors. Those degradations will impact the radar range, the main radar axis (BSE) and the radar detection quality (resolution, ambiguity, discrimination).

Development tools and methods, such as simulation, are increasingly important to face and address the pressure of innovation.
