“…Finally, a low noise amplifier with a sharp filter is connected to the IF output (see Figure 5) of the mixer in order to adapt to the dynamics of the useful signal. Note that the use of a standard spectrum analyzer could replace the receiving device, but it would be much less effective in terms of sensitivity [6] and [8]. Figure 6 displays the electronic board (DUT) located in the MSRC and to be characterized in terms of radiated EM susceptibility.…”

Abstract-The objective of this paper is to propose an improved approach based on a novel nonintrusive method for easily assessing the high frequency CW EM radiated susceptibility of an electronic system by characterizing its nonlinear electromagnetic effects. For this purpose, we have developed a specific harmonic frequency detection system coupled with a mode stirrer reverberating chamber. We describe the principles of the method and study a generic device board which is representative of a real electronic system. We evaluate the EM susceptibility of a micro controller in full functional mode and the data exchanges with two types of external 8 Mb SRAM memories. We observe the EM radiated susceptibility of this device by a functional EMC analysis method; then we measure the harmonic frequency content and make a correlation with the EM susceptibility results. We obtain significant differences between the two memory devices, as a consequence of their different managements of internal voltage over stress. We are well aware that this method is currently not validated in industrial environments EMC. In this paper, we only want to show that the appearance of the highest harmonic level occurs only when DUT has the highest functional failure.

“…odometry using inertial sensors and a polarized light compass [15]) to navigate in the field. It may also be possible to externally localize the MAVs from the hive using RF triangulation or harmonic radar [18]. This information could be used to update the MAVs in flight or correlate sensor readings with a location when the drones return.…”

Research in micro-aerial vehicle (MAV) construction, control, and high-density power sources is enabling swarms of MAVs as a new class of mobile sensing systems. For efficient operation, such systems must adapt to dynamic environments, cope with uncertainty in sensing and control, and operate with limited resources. We propose a novel system architecture based on a hive-drone model that simplifies the functionality of an individual MAV to a sequence of sensing and actuation commands with no in-field communication. This decision simplifies the hardware and software complexity of individual MAVs and moves the complexity of coordination entirely to a central hive computer. We present Karma, a system for programming and managing MAV swarms. Through simulation and testbed experiments we demonstrate how applications in Karma can run on limited resources, are robust to individual MAV failure, and adapt to changes in the environment.

“…T HANKS to their inherent high robustness to radar clutter interference, harmonic radar systems have been proposed for years in scenarios where the strong unwanted reflections caused by the environment would have blinded traditional isofrequency radars, such as anticollision automotive systems [1], insect tracking [2], and avalanche victims detection [3]. Recently, harmonic-based wireless sensors suitable for Internetof-things (IoT) applications have been investigated in order to harness their potentiality in terms of low power and long read range [4]- [6].…”

“…All these three elements are designed to be matched to an impedance of 50 Ω. Although this approach might be suboptimal in terms of power efficiency and area occupation with respect to the single dual-frequency antenna approach (see [2] and [7]), it allows for an independent design and test of each element, and makes it feasible and straightforward to add circuits and sensing blocks between the antennas and the frequency doubler, thus leading to a scalable harmonic platform, as demonstrated in [4]- [6].…”

Abstract-In this letter, the design and performance analysis of a harmonic planar transponder on paper, which conjugates compactness and scalability, are presented. The tag, targeted for a fundamental frequency of 1.2 GHz, is based on a frequency doubler with a single lumped component (a low-barrier Schottky diode) and a system of nested tapered annular slot antennas. Both antennas, orthogonally placed, feature a maximum gain around 3 dBi. The frequency doubler is optimized for power levels in the order of −13 dBm, where it achieves a conversion loss of 15.7 dB. A complete prototype has been tested in a wireless indoor experiment, demonstrating a coverage of at least 4 m, insensitive to tag-toreader rotations (transmitter effective isotropic radiated power 16 dBm).
