Analyzing Radar Cross Section of Large Targets in ANSYS HFSS - White Paper

This paper describes the utilization of ANSYS HFSS with the novel HFSS SBR+ solver to analyze, predict and optimize radar signatures of electrically large targets and scenes. Subject models include targets such as aircraft, missiles, rockets and ships. In addition, the paper describes how electromagnetic simulations with ANSYS HFSS also provide deep field-level insight into electromagnetic interactions that contribute to radar scattering.

Autonomous Vehicle Radar: Improving Radar Performance with Simulation - White Paper

As the world draws near to the reality of fully autonomous automobiles and transport vehicles, there is a great deal of focus on the development of artificial intelligence (AI), machine learning and rapid automated decision-making. These solutions are aimed at duplicating — and improving upon — a human’s ability to perceive the world around them, and at efficiently and safely guiding a vehicle through a journey. A critical aspect of autonomous vehicle control is the continued evolution of vehicle sensors — the eyes and ears of the control system that perceive the operational characteristics of the vehicle and the environment around us. While the AI and decision-making systems must plan the vehicle trajectory and response to the environment, the sensors must feed the control systems executing those algorithms with accurate data on the current and developing state of the vehicle’s surroundings. The development of accurate algorithms depends in part upon the availability of accurate sensor data.

混合有限元边界积分法

随着近期积分方程求解效率的提高,现在我们可以在混合有限元边界积分法(FEBI)中将积分方程法和有限元法相结合(FEM)[1]。在电磁学中,FEM是一种通用技术,该技术既支持体积电场求解,又能精确地描述微波组件、天线和信号完整性问题[2,3]。对于天线或散射问题,必须包含围绕模型的空气域,并且用吸收边界条件(ABC)予以闭合。虽然用于直接求解对象表面电流的积分方程(IE)方法不如FEM通用,但它在解决大型开放问题时往往效率更高,因为它不需要周围的空气体积。通过在FEBI方法中结合这两种方法,HFSS用户能够准确高效地仿真非常复杂的大型开放性问题。HFSS™的13.0版将提供这种新方法。

利用3D电磁场仿真工具开展板上封装仿真

多年以来,设计人员在仿真中考虑到了封装寄生参数的影响,从使用理想电感+电阻等简单的一阶模型到更为复杂的Spice梯形网络直至最后使用3D电磁场仿真器完整抽取封装的S参数。对于封装和PCB通道相结合的情况,目前最常用的方法是分别抽取封装和电路板作为S参数模型或宽带SPICE模型,然后在电路仿真器中将这两种模型结合起来。由于工作频率不断升高、信号速度不断加快、集成器件日益复杂等因素,这种方法也暴露出越来越多的局限性。

Energy Efficient, IoT-Based Smart Home - White Paper

"Smart Home" technology is the future of residential technology, designed to deliver and distribute a number of services inside and outside the house via networked devices in which all the different applications and the intelligence behind them are integrated and interconnected. These smart devices have the potential to share information with each other as long as they can access a broadband internet connection. Hence, "Smart Home" technology has become part of the IoT (Internet of Things). In this work, we analyze a home model to demonstrate an energy-efficient IoT-based smart home. We perform multiphysics simulations focusing on the kitchen of the home model, and use a motion sensor with a surveillance camera as part of the home security system. Coupled with the home light and HVAC control systems, the smart system can remotely control the lighting and heating or cooling when an occupant enters or leaves the kitchen.
