“…These two sensing methods can also be combined to create an FSS that is capable of sensing multiple parameters simultaneously, which is especially useful in cases where one needs to understand the effect of one parameter on another like is the case with strain and temperature [227]. Beyond temperature and strain sensors, FSSs have also been used for crack detection and materials characterization [228–231].…”

Microwave and millimetre-wave non-destructive testing and evaluation (NDT&E) has a long history dating back to the late 1950s (Bahr 1982 Microwave non-destructive testing methods ; Zoughi 2000 Microwave Non-destructive testing and evaluation principles ; Feinstein 1967 Surface crack detection by microwave methods ; Ash 1973 In 3rd European Microwave Conference ; Auld 1981 Phys. Technol. 12 , 149–154; Case 2017 Mater. Eval. 75 ). However, sustained activities in this field date back to the early 1980s (Zoughi 1995 Res. Nondestr. Eval. 7 , 71–74; Zoughi 2018 Mater. Eval. 76 , 1051–1057; Kharkovsky 2007 IEEE Instrumentation & Measurement Magazine 10 , 26–38). Owing to various limitations associated with using microwaves and millimetre waves for NDT&E, these techniques did not see much utility in the early days. However, with the advent and prevalence of composite materials and structures, in a wide range of applications, and technological advances in high-frequency component design and availability, these techniques are no longer considered as ‘emerging techniques’ (Zoughi 2018 Mater. Eval. 76 , 1051–1057; Schull 2002 Nondestructive evaluation: theory, techniques, and applications ). Currently, microwave and millimetre-wave NDT&E is a rapidly growing field and has been more widely acknowledged and accepted by practitioners over the last 25+ years (Case 2017 Mater. Eval. 75 ; Bakhtiari 1994 IEEE Trans. Microwave Theory Tech . 42 , 389–395; Bakhtiari 1993 Mater. Eval. 51 , 740–743; Bakhtiari 1993 IEEE Trans. Instrum. Meas. 42 , 19–24; Ganchev 1995 IEEE Trans. Instrum. Meas. 44 , 326–328; Bois 1999 IEEE Trans. Instrum. Meas. 48 , 1131–1140; Ghasr 2009 IEEE Trans. Instrum. Meas. 58 , 1505–1513). Microwave non-destructive testing was recently recognized and designated by the American Society for Nondestructive Testing (ASNT) as a ‘Method’ on its own (Case 2017 Mater. Eval. 75 ). These techniques are well suited for materials characterization; layered composite inspection for thickness, disbond, delamination and corrosion under coatings; surface-breaking crack detection and evaluation; and cure-state monitoring in concrete and resin-rich composites, to name a few. This work reviews recent advances in four major areas of microwave and millimetre-wave NDT&E, namely materials characterization, surface crack detection, imaging and sensors. The techniques, principles and some of the applications in each of these areas are discussed. This article is part of the theme issue ‘Advanced electromagnetic non-destructive evaluation and smart monitoring’.

“…To overcome this problem, structural health monitoring (SHM) systems have been introduced since the systems have great potential to enhance the regular operation and maintenance of structures like tunnels, buildings, bridges and others. The purposes of the SHM are damage analysis, damage localization and estimating the remaining lifetime of the structure [2][3]. The damage was determined by changes in the modal parameters like frequencies which were gained from measured time histories.…”

Structural health monitoring (SHM) technologies have attained attention to monitor civil structures. SHM sensor systems have been used in various civil structures such as bridges, buildings, tunnels and so on. However the previous sensor for SHM is wired and encounter with problem to cover large areas. Therefore, wireless sensor was introduced for SHM to reduce network connecting problem. Wireless sensors for Structural Health monitoring are new technology and have many advantages to overcome the drawback of conventional and wired sensor. This project proposed passive wireless SHM sensor using frequency selective surface (FSS) as an alternative to conventional sensors. The electromagnetic wave characteristic of FSS will change by geometrical changes of FSS due to mechanical strain or structural failure. The changes feature is used as a sensing function without any connecting wires. Two type of design which are circular ring and square loop along with the transmission and reflection characteristics of SHM using FSS were discussed in this project. A simulation process has shown that incident angle characteristics can be use as a data for SHM application.

“…In consequence, a new solution of technologies for modern building is proposed the FSS to overcome this problem. The presence of electromagnetic wave of frequency selective surface will vary the frequency change of FSS due to block signal from outside and inside the building [12].…”

<span>The use of energy saving glass has become very popular in the modern day building design. This energy saving property is achieved by applying a very thin tin oxide (SnO2) coating on one side of the glass. This coating can provide good thermal insulation to the buildings by blocking infrared rays while being transparent to visible part of the spectrum. Drawbacks of these energy saving windows is that it also attenuates the transmission of useful microwave signals through them. These signals fall within the frequency band of 0.8GHz to 2.2GHz. In order to pass these signals through the coated glass, the use of aperture type frequency selective surface (FSS) has being proposed. In the present work, SnO2 thin film with FSS structure was fabricated. Microwave transmission through SnO2 coated glass with FSS structure was also analyzed using network analyzer. The result of computer simulation was confirmed and consistent with the network analyzer results that showed the improvement of SnO2 coated glass with the FSS structure.</span>
