Wireless Power Transfer (WPT)

Wireless power transfer (WPT) is much researched and discussed in the context of IoT, electric vehicles and mobile electronic devices. The methodology of powering a device without a physical connection is well known. However, designing the coil shapes and their placement, maximizing efficiency and validating behavior at the system level still represent challenges that cannot be achieved without simulation. The next frontier to be explored is extending and applying wireless power transfer systems to more applications, such as continuous charging of multiple devices, increasing the range of efficient power transfer and ensuring the WPT system design meets regulatory guidelines.

Internet of Things – Making Wireless Happen

internet of things wireless office antennaWireless communication is changing our world. The number and density of antennas in our immediate surroundings have exploded, and are increasing every day. There are literally hundreds of antennas in a typical home and thousands in an office building. Driven by the demands of the Internet of Things, along with autonomous vehicles and electrification initiatives in the aerospace sector, more antennas are required to be integrated into our devices to make all of this wireless interconnectivity possible.

Connected Car Technology: Making it Safe and Reliable

Connected Car Image 01The internet has now come to the automobile, bringing connectivity for infotainment, telematics and vehicle data analytics. The connected car is rapidly becoming a key node in the emerging Internet of Things. While connected car technology is a delight for car buyers, it poses unprecedented new engineering challenges for car manufacturers of reliability, safety and security. Continue reading

Santa Struggles with Radio Frequency Interference – Could Hinder Gift Delivery

Santa Calling about Radio Frequency InterferenceWhen my caller ID lit up showing an incoming call from “The North Pole” I scratched my head wondering who it could be. Only one person I know of lives at The North Pole. Yup, it was Santa. In the past, Santa has worked with ANSYS engineers to improve the structural and aerodynamic properties of his sleigh. This year, Santa had another concern that he was calling me about. It seems that on some test flights in preparation for this year’s Christmas Eve deliveries, Santa noticed that the sleigh’s on-board GPS radio that he and his elves rely on for accurate tracking information wasn’t always working properly. Santa noticed that the problem usually occurred when he flew near cell phone base station towers. We assured Santa that we could help and we set about modeling the installed radio frequency (RF) systems on his sleigh in order to understand what was happening. Continue reading

I Can’t Hear You! Radio Frequency Interference (RFI) in Sports Arenas

During a recent NFL game, the visiting team complained about picking up the home team’s radio broadcast on their coach-to-coach headsets preventing the coaches from communicating with one another. The home team indicated that there were also issues communicating with the quarterback using their radio system.

RF interference stadiumsRadio frequency interference problems in major sports stadiums are unfortunately very common given the large number of radios present in a relatively small area. A typical sports stadium includes systems transmitting and receiving signals for game day operations, referee and commercial coordination, coach and player communication, a variety of cell phone networks, Wi-Fi services, and a number of other wireless services.

Making Our Highways Safer with Automotive Radar

image002Automotive radar is a key technology in delivering active safety systems that play a major role in reducing traffic fatalities. Active safety systems include adaptive cruise control and collision warning systems with automatic steering and braking intervention, lane departure warning and electronic stability control. In a collision warning system, the automotive radar consisting of a 77 GHz transmitter emits signals that are reflected from objects ahead, at the side and to the rear of the vehicle and are captured by multiple receivers integrated throughout the vehicle. The radar system can detect and track objects and trigger a driver warning of an imminent collision and initiate electronic stability control intervention.  Continue reading

Solving the Impossible Electromagnetic Simulation with HPC

solving impossible electromagnetic simulation

I was speaking with an ANSYS HFSS developer about a year ago when he mentioned they were starting to see customers who wanted to run 3-D full wave electromagnetic field simulations that would need more than a terabyte of computer system memory, something this developer hadn’t been able to do before. Continue reading

Bigger, Faster Antenna and Antenna Platform Simulations!

The recent ANSYS acquisition of Delcross Technologies is a very exciting addition to our electronics product portfolio! The Internet of Things (IoT), aerospace and defense electronics, including unmanned aerial vehicles (UAVs), automotive radar and autonomous vehicles all have increasing use of multiple antennas and wireless services.

logo_delcross_2ANSYS HFSS delivers capabilities that enable antennas to be placed on complex structures followed by efficient simulation using component library models with encryption, assembly modeling with mesh assembly, and advances in our hybrid solver technology. The next logical step in HFSS development is to perform even larger platform-level simulations. To solve larger problems requires leveraging asymptotic methods of which one of the most powerful and effective method is the Shooting and Bouncing Ray (SBR) technique. The Delcross implementation of the SBR technique and its integration with high-level system analysis is the most advanced in the world and is now a part of the ANSYS product portfolio! ANSYS has fast-forwarded its development plan and will now offer our customers the ability to solve massively large antenna simulations; installed antenna performance and system RF co-site problems.

GPU Acceleration of ANSYS HFSS Transient at NVIDIA GPU Technology Conference (GTC) 2015

The paradigm of supercomputing has shifted rapidly during the past decade. Ten years ago when we heard “NVIDIA”, immediately we associated the brand name with computer graphics, games and animation. NVIDIA’s breakthroughs in graphics processing unit (GPU) technology make supercomputing inexpensive and widely accessible nowadays. In addition to its visual computing leadership, NVIDIA also strives for green computing where its hardware design aims at the best performance per watt. More than eight teraflops of computing power can be achieved on an NVIDIA Tesla K80 that consumes less than 300 watts of electricity. Continue reading
