Stochastic electromagnetic fields can be described by the auto- and cross correlation spectra of the electric and magnetic field values at pairs of points in space. In this work the characterization of noisy electromagnetic fields by sampling the field values in pairs of sampling points is discussed. Sampling of the electric or magnetic field values in all pairs of a set of sampling points yields the correlation matrix of the field samples. If the near-field in a surface of reference enclosing the stochastic field sources is sampled and characterized by its correlation matrix the field radiated in the space outside the surface of reference can be calculated and described by the field correlation spectra. Depending on the number of statistically independent field sources the eigenvalue decomposition of the correlation matrix yields a compact description of the measured EM noise field.

A new long-distance microwave reading system is introduced, that we shall call RID (Remotely Identify and Detect), able to locate and identify objects in harsh indoor environments. This is obtained by augmenting standard RFID reader operations with the mono-pulse RADAR principle and electronic beam scanning capabilities. In this way reading failures due to operation in severe fading environments are effectively overcome. The technique is experimented at 2.45 GHz and may be frequency-scalable: the higher the operating frequency the closer can be the tags to be detected. The system is realized by a suitable combination of custom designed components, such as a double printed-monopole array with electronic scanning capability, and of low-power commercial transceivers and MCUs. This results in an handheld low cost device with total dimensions comparable with typical PDAs. The system capabilities are demonstrated in indoor scenarios locating and selecting closely-spaced tagged items, fixed or moving. From this view point RID could be an answer to the intense research and industrial interest solicited by the needs of interacting with systems of devices, such as sensors and actuators, capable of improving the living conditions both at home and in a work space.
介绍了一种新的远距离微波读取系统，我们称之为RID (remote Identify and Detect)，它能够在恶劣的室内环境中定位和识别物体。这是通过增加标准RFID阅读器操作与单脉冲雷达原理和电子束扫描能力获得的。通过这种方式，有效地克服了在严重衰落环境中操作所导致的读取故障。这项技术在2.45 GHz的频率上进行了实验，并且可以进行频率扩展:工作频率越高，被检测到的标签就越近。该系统是通过定制设计元件的适当组合来实现的，例如具有电子扫描功能的双印刷单极子阵列，以及低功耗商用收发器和mcu。这导致手持低成本设备的总尺寸与典型的pda相当。该系统的功能在室内场景中进行了演示，用于定位和选择固定或移动的紧密间隔标记物品。从这一观点来看，RID可以回答由于需要与诸如传感器和执行器等设备系统相互作用而引起的激烈研究和工业兴趣，这些设备能够改善家庭和工作空间的生活条件。

As demonstrated in this study, bonding TPG with CTE-matched alloys, such as MoCu, simultaneously achieves high thermal conductivity (TC > 900 W/m-K) and low coefficient of thermal expansion (CTE < 9×10−6/K). The TC and CTE measurements as a function of TPG loadings on the TPG-MoCu composites match the theoretical calculation. Compared with the traditional 2-component architecture, heat spreaders made of this TPG composite not only increase the efficiency of thermal spreading, but also eliminate one thermal interface and reduce the integration cost.

We report, for the first time, the benefit of RF burn-in at power levels significantly higher than the nominal handling capacity of micro-electromechanical capacitive switches. The benefit appears to be permanent, so that, after burn-in, the switches remain less vulnerable to dielectric charging and, presumably, more reliable. It was speculated that high RF power permanently changed the bond configuration of the silicon-dioxide dielectric, which prevented charge injection under DC bias. Obviously, more detailed study is needed to elucidate the detailed burn-in mechanism. However, this initial result is very encouraging and can facilitate the application of these switches in many RF systems.

A wireless data link using active MMIC components at a carrier frequency of 220 GHz is supporting record data rates of up to 30 Gbit/s. The paper presents receiver sensitivity measurements for data rates up to 30 Gbit/s and wireless data transmission experiments for distances up to 20 m. For this distance a 231 – 1 bit pattern with a data rate of 15 Gbit/s was transmitted. For a transmission distance of 10m it was possible to transmit a 25 Gbit/s signal.

The class-B/J mode continuum in power amplifiers (PAs) defined at the current source plane is discussed considering different parasitic elements including CDS as well as the package. Based on this realistic device description the change of the continuous load impedances depending on the reference plane is demonstrated. It is shown that the design flexibility predicted by the continuous mode theory decreases if the transistor package is taken into account. The presented investigations provide the basis for the design of a broadband GaN PA. In the frequency range of 0.9 GHz to 1.8 GHz, this PA achieves a saturated output power of more than 70 W with an efficiency η of 56–63 %. In the extended frequency band up to 2.3 GHz an output power of still 60 W with 53 % drain efficiency is available.

Recently a new systematic design rule was proposed to realize high-order UWB bandpass filters using cascaded E-shape microstrip structures. The responses of these miniaturized filters show one transmission zero at the upper stop-band. In order to improve the selectivity at the lower stop-band, this paper proposes a new generation of miniaturized high-order UWB bandpass filters having an attenuation pole in the lower stopband. The filters, employing the E-shape microstrip structure, are the cascade of third-order UWB bandpass filters electromagnetically coupled through λ/4 microstrip lines realised on the dielectric superstrate of the structure. A high selectivity sixth-order UWB bandpass filter is designed, simulated, fabricated and measured. The dimension of the filter is about 4 mm × 6 mm × 0.5 mm excluding the feeding ports. The results from the simulation and measurement show good agreement. It is observed that this filter has attenuation better than 40 dB immediately after the passband, and over a large frequency range in the lower and upper stop bands.

The implementation of a voltage controlled current source (VCCS) in full-wave electromagnetic simulation using finite-difference time-domain (FDTD) is introduced. The VCCS is used to model a metal oxide semiconductor field effect transistor (MOSFET) commonly used in microwave circuits. This new approach is verified with several numerical examples including circuits with VCCS and MOSFET. Good agreement is obtained when the results are compared with those based on analytical solution and PSpice.

A modified piece-wise polynomial pre-distortion is proposed, investigated and compared against classic memoryless polynomial pre-distortion. The proposed enhanced piece-wise polynomial pre-distortion uses the overlap between segments to ensure continuity in the total pre-distortion function. The implementation of overlap allows the use of a simple error estimation algorithm to minimise hand over error. The classic and proposed piece-wise pre-distortion performances are assessed and compared for several sets of polynomial coefficients. The proposed method is shown to consistently outperform classical polynomial pre-distortion in terms of required coefficients and linearity improvement. The method is applied for the linearisation of an envelope tracking Class-J PA at 1.7GHz, under a 1.4MHz LTE signal with a 14.4dB PAPR.

This paper illustrates the potential of microwave frequencies for biological analysis. Once penetrating inside biological cells, microwaves can interact with their intracellular content and inform on their safe or malignant state. This work demonstrates that their cancer grade (i.e. aggressiveness level) can also be identified by this way. Hence, based on permittivity measurements on three colon cancer cell lines loading RF resonators, the presented results show significant differences of electromagnetic signature in the cancer grade of analyzed cells. This sensing method appears very promising to develop new powerful tools for early cancer diagnostic.
