Co-Site Interference & Lightning – APS/MTT Chapter Meeting
October 9, 2018 @ 6:00 PM - 7:30 PM
Interference between RF devices is one of the biggest challenges in designing and maintaining commercial and defense systems. These systems include ships, airplanes, drones, cell phones, satellites, automobiles and generally, anything that has RF systems installed in or on it. The problem is complex for a number of reasons including the broadband nature of the interference, the lack of detailed performance data, introduction of intermodulation products when multiple systems interact with one another and a host of other reasons. Identifying and solving cosite interference issues early in a design is critical as discovering an interference problem right before bringing a product to market or after it has been put into service can cost millions of dollars to fix the problem and lost revenue. One only has to perform a web search for “cosite interference” to see a sample of the issues that have plagued military and commercial programs for decades. In this talk, we will discuss the analysis capabilities and approach that EMA employs to predict and mitigate RF cosite interference problems for our customers.
Today, EM engineers must use 3D geometry in a practical way in their work without letting the complexity of handling the full CAD overwhelm their design cycles. EM effects teams must do more in an increasingly shorter period, while being required to work on models traceable to the master CAD. As the ability to model ever-larger scenarios with 3D computational electromagnetic (CEM) codes emerges as a possibility, the main limitation is preparing the geometrical models received from mechanical drawings in PLM systems in a timely manner. This talk will talk about best practices to develop EM models that can have an impact on product design in EM effects. We will discuss common scenarios for aircraft, spacecraft and automobiles and how modern EM effects teams can leverage simulation to reduce the design cycle and achieve product validation.
