Wireless Power Transfer and Microwave Energy Harvesting

<p> Although wireless energy transfer is an old idea (Tesla patented one design in 1901), technological advances and the rise of portable devices have made it relevant again for different applications, such as wireless charging and energy harvesting. This webinar will consist of two parts. The first part is a review of low frequency power transfer in two categories: short range-inductive charging and powering of electronic devices and electric vehicles, and mid-range power transfer through coupled resonant circuits. The second part of the webinar is concerned with wireless energy transfer over longer distances, where the far-field transfer of RF energy may be used.</p>

EM Simulation for Space Applications

<p> Satellites provide a challenging environment for electromagnetic components and antennas. The limited available space has to be shared by multiple tightly-clustered systems that have to operate correctly in extreme thermal conditions. Electromagnetic simulation plays a critical role in ensuring that mission-critical components work as intended once in orbit. This webinar will give an overview of how the range of simulation tools in CST STUDIO SUITE&reg; can be used to design and optimize antennas and components quickly and with high accuracy.</p>

Electromagnetic Simulation of Composite Materials and Cable Harnesses in Aircraft

<p> This webinar will discuss efficient EM modeling techniques for simulating composite materials such as carbon fiber laminates at the full aircraft level. The impact of composite materials on electromagnetic effects including installed antenna performance and lightning strikes will be explored. The webinar will also highlight recent advances in cable harness modeling and the effect of different shielding and grounding/bonding schemes for installation in aircraft.</p>

MIMO Antenna Systems Advanced Communication

<p> Multiple-input, multiple-output (MIMO) systems are a major field of study for researchers interested in achieving high data rate communication in typical urban multi-path environments. This webinar will show how simulation can be used to calculate the effect of hand and head (e.g. CTIA models) on mobile devices, MIMO for wearable antennas and different power weighting functions for different environments, along with post-processing options for envelope correlation (including spatial power weighting functions), derived quantities&nbsp; diversity gain and multiplexing efficiency.</p>

Efficient Electromagnetic Simulation of Shielding Mechanisms in Microwave Ovens

The door to a microwave oven forms part of the heating cavity, allowing access to the oven interior. The seal around the door is never perfect, so electromagnetic fields will leak out of the oven, potentially interfering with other electrical equipment or exceeding safety limits for power levels in human operators. Oven designs have to meet legal requirements for the amount of power which can leak beyond a certain distance from the oven (due to human exposure concerns), and also have to meet electromagnetic compatibility (EMC) requirements. This article discusses how electromagnetic simulation can be used to design effective shielding mechanisms in order to adhere to these standards.

Analyzing Power Integrity Issues from Power Plane Interaction

When a printed circuit board (PCB) includes a power plane that is near to signal traces or other power planes, there is a significant risk of energy transfer between parts of the system. Not only does this coupling lead to power switching noise being transferred into data signals, it also means that power supply systems may demonstrate additional resonances that are not seen in the individual components. This can affect the power integrity of the PCB and may reduce its speed or reliability. This paper will explore some of the potential power integrity issues that can affect a PCB and explain how simulation can be used to help reduce these effects.
