“…Hoeft and Hofstra [20] [20] obtained a square root dependence on frequency which is consistent with the skin depth approximation of slot impedance Z^in eq (24) . Faught [14] measured the transfer impedance of a number of gasket materials in a coaxial fixture for frequencies from 0.1 to 1000 MHz.…”

“…The most comprehensive attempt at characterizing gaskets by different methods [5] included a shielded room with an aperture [1], nested reverberation chambers [20], a coaxial transfer impedance fixture [3], and a modified ASTM coaxial holder [3]. The discouraging lack of agreement between the four methods on several gaskets is best described by quoting from [5] could be that none of the four methods as performed in [5] uses a reference measurement in the absence of the gasket only.…”

“…This paper is dedicated to the lightning protection of the sensor, as it has sensitive electromagnetic field interfaces and it is also placed in close proximity to the power conductor. The concentrator falls in a more general category of electronic equipment that has been treated elsewhere, e.g., [2] and [3].…”

This paper presents the design procedures implemented in a power line sensor in order to make it compatible with the electromagnetic environment, especially to the stresses imposed by lightning flashes. The paper includes the sensor description and simulation results of lightning surges coupled to the device by its external interfaces. It is shown that the protection of the radiofrequency circuitry requires the installation of a high-pass filter at the antenna port and that the protection of the voltage-measuring circuit can be accomplished by using a voltage divider combined with low-pass filter. By its turn, the protection of the current-measuring circuit is achieved by the installation of surge protective components.

“…The latter utilizes the influence of metal/water on the performance of the tag to sense the object’s property change. The inference of metal/water on the tag can be equivalent to adding an inductance in parallel with the circuit of the tag (Hoeft and Hofstra, 1988; Sunny et al , 2016). For example, once the metallic object’s property has changed, the value of parallel inductance will be altered at the same time, which can be detected by analyzing the sensing parameters captured by the reader or other matching equipment.…”

Purpose Radio frequency identification tags for passive sensing have attracted wide attention in the area of Internet of Things (IoT). Among them, some tags can sense the property change of objects without an integrated sensor, which is a new trend of passive sensing based on tag. The purpose of this paper is to review recent research on passive self-sensing tags (PSSTs). Design/methodology/approach The PSSTs reported in the past decade are classified in terms of sensing mode, composition and the ways of power supply. This paper presents operation principles of PSSTs and analyzes the characteristics of them. Moreover, the paper focuses on summarizing the latest sensing parameters of PSSTs and their matching equipment. Finally, some potential applications and challenges faced by this emerging technique are discussed. Findings PSST is suitable for long-term and large-scale monitoring compared to conventional sensors because it gets rid of the limitation of battery and has relatively low cost. Also, the static information of objects stored in different PSSTs can be identified by a single reader without touch. Originality/value This paper provides a detailed and timely review of the rapidly growing research in PSST.
