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.

Wireless 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.

It isn’t too much of a stretch to say that Moore’s Law can be credited with many of our technological advances. Since the 1960s, Gordon Moore’s prediction that computing performance will double every 12 to 18 months has been accepted as gospel. And the proof is all around us. The conveniences of the modern world — ubiquitous communication through Internet enabled phones, electronic payments, and digital streaming, to name just a few examples — are all due to continuous engineering innovations delivered through cheaper, faster, more precise electronics.

“I feel the need. The need for speed!” is a famous line from the movie Top Gun. Designers of electric motors, power transformers, planar transformers, and actuators — or anyone that regularly runs transient electromagnetic field simulations — can relate to that phrase. Transient electromagnetic field simulation is a powerful, accurate method to solve EM problems in the time domain, but the process is painfully slow even with today’s fastest computers. Thus, EM transient simulations often are relegated to the verification stage rather than the design stage of the device. With ANSYS Maxwell in ANSYS 17.0, you can now channel your inner Tom Cruise — ANSYS delivers on your need for speed! Continue reading
In the five short years that I have been in the RF and Microwave design industry, I have seen the demand (and need) for quick and accurate electronic design simulations escalate rapidly. I have also had the opportunity to interact with many design engineers during this time who have come to the same conclusion – they need more accuracy. Whereas ideal component simulation models or s-parameter files were once acceptable, this is much less often the case now. Parasitics have a considerable effect on component response, and even more so as design frequency increases. Labor and material costs multiply with each design iteration, so it is very important to limit these cycles and achieve a successful design early on. Continue reading
Delivering a truly innovative product for the mobile revolution requires optimization at every level of design for power, performance, thermal and structural integrity. The success of today’s electronic products are tied to the success of their entire system, including all components from antenna to board, and from chip to chassis. Designing a smart watch, for example, requires multiple iterations of chip, package, board, antenna, and cooling strategy to arrive at a final optimized product. Continue reading
Product development of today’s complex mobile and IoT devices requires the cooperation of independent design teams working at the chip, package, and system level. However, several roadblocks in the electronics design flow make this cooperation very difficult, impacting time, effort, and ultimately the cost required to deliver a successful product to market.

When 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
Healthcare is often cited as one of the leading applications for the Internet of Things (IoT). Looking around the Web, it is clear that leading high tech companies like Qualcomm, Intel, Cisco, Juniper all have initiatives on healthcare. A notable example is Google, which has already created a prototype contact lens to help measure glucose levels in diabetic patients.
“Better patient outcome” is a goal that all of us can get behind!
But even the most successful high-tech companies are quickly discovering that designing medical devices is different than designing consumer electronics. Designing for the healthcare industry requires extra rigor, insight, and collaboration with healthcare industry experts. Continue reading
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.
Radio 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.
