Introduction To Electromagnetic CompatibilityJim Jenkins
Here are a few key points about ground in the context of electromagnetic compatibility (EMC):
- Ground is a common reference point in an electrical system that all other voltages are measured against. It establishes a baseline voltage level.
- In EMC, ground plays an important role in providing a return path for electromagnetic interference (EMI) currents. These currents, known as common mode currents, flow on cables and are looking for a way to complete their circuit back to the source.
- An ideal ground would have zero impedance and instantly drain away any EMI currents. In reality, all grounds have some finite impedance that can allow currents to couple into other circuits.
- Different grounding schemes are used, such

How can variables be measured in environments that are too hot, too cold, or moving too fast for traditional circuit-based sensors? A new technology for obtaining multiple, real-time measurements under extreme environmental conditions is being developed under Phase 1 and 2 funding contracts from NASA's Kennedy Space Center’s Small Business Technology Transfer (STTR) program. Opportunities for early deployment licensing and Phase 3 STTR contracts are now being accepted.
Passive, remote measuring systems can be created using new Orthogonal Frequency Code (OFC) multiplexing techniques and specially developed, next-generation SAW sensors. As a result, very cost-effective applications such as spaceflight sensing (for instance, temperature, pressure, or acceleration monitoring), remote cryogenic fluid level sensing, or an almost limitless number of other rigorous monitoring applications are possible.
Screaming Channels: When Electromagnetic Side Channels Meet Radio TransceiversPriyanka Aash
The drive for ever smaller and cheaper components in microelectronics has popularized so-called "mixed-signal circuits," in which analog and digital circuitry are residing on the same silicon die. A typical example is WiFi chips which include a microcontroller (digital logic) where crypto and protocols are implemented together with the radio transceiver (analog logic). The special challenge of such designs is to separate the "noisy" digital circuits from the sensitive analog side of the system.
In this talk, we show that although isolation of digital and analog components is sufficient for those chips to work, it's often insufficient for them to be used securely. This leads to novel side-channel attacks that can break cryptography implemented in mixed-design chips over potentially large distances. This is crucial as the encryption of wireless communications is essential to widely used wireless technologies, such as WiFi or Bluetooth, in which mixed-design circuits are prevalent on consumer devices.
The key observation is that in mixed-design radio chips the processor's activity leaks into the analog portion of the chip, where it is amplified, up-converted and broadcast as part of the regular radio output. While this is similar to electromagnetic (EM) side-channel attacks which can be mounted only in close proximity (millimeters, and in a few cases a few meters), we show that it is possible to recover the original leaked signal over large distances on the radio. As a result, variations of known side-channel analysis techniques can be applied, effectively allowing us to retrieve the encryption key by just listening on the air with a software defined radio (SDR).

Interference limits the capacity of cellular radio systems by creating bottlenecks that reduce performance. The two primary types of interference are co-channel interference, which occurs between cells using the same frequencies, and adjacent channel interference, which occurs between nearby frequency channels. Managing interference is important for cellular system design in order to minimize cross-talk and missed/blocked calls.
KinPhy is a kinetic in-band channel for millimeter-wave networks that uses physically oscillating metasurfaces to backscatter information to an mm-wave router (1). It consists of a metasurface and radar reader (2). The metasurface precisely modulates the phase of reflected mm-wave signals using piezo actuators, while the reader shines a mm-wave signal onto the surface and decodes the backscattered signal (3). Evaluation shows the system can accurately detect metasurfaces at distances up to 5m indoors, even when non-line-of-sight or facing away, demonstrating potential for applications like spontaneous authentication and security.
Radar and secondary radar systems use radio waves to detect objects and provide essential information to operators. Radar works by transmitting radio waves that bounce off targets and are received, allowing calculation of range and position. Secondary radar requires aircraft to carry transponders that respond to interrogations by transmitting a coded reply signal carrying additional data like identification and altitude. This improves detection range and allows transmission of emergency information.
