This Special Issue is based on the adopted inspection methodology and further classified into microwave, tera hertz, thermal, optical, electrical, and acoustical non-destructive testing techniques. A brief description of the accepted papers is as follows: Microwave NDT The paper by Varshney et al. [1 ] demonstrates applications of RF technology for non-destructive testing of the quality of coconut by dielectric sensing, whereas Jue Lyu et al. present a reconstruction algorithm for higher resolution image from under-sampled measurements by a compressive 2D near-field MMW super-resolution (SR) imaging model [2 ]. The paper by Sharma et al. discusses the design, fabrication, and non-destructive measurement of an active frequency selective surface (FSS) embedded tuneable radar absorber [3 ]. In [4 ], Matsukawa presents the utilisation of time-domain responses of microwave guided-modes propagating along fibreglass-reinforced plastic mortar pipelines for non-destructive inspection of underground pipelines, whereas Pandit et al. demonstrate a non-destructive microwave resonant sensor for detecting the aqueous bio-chemicals in [5 ]. Tera Hertz NDT In [6 ], Saqueb, Nahar and Sertel present a rail-based THz SAR imaging system capable of capturing images of concealed objects behind a dielectric material layer. Thermal NDT In [7 ], Kaur and Mulaveesala provide an insight into the selection of independent components for inspection of mild steel samples using infrared thermography for detection of flat bottom hole defects, while in [8 ] Nie, Luo and Li present the solution for the intelligent inspection of the hotspot with an unmanned aerial vehicle in the large-scale photovoltaic plant. In [9 ], Rani and Mulaveesala highlight the testing and evaluation of glass fibre-reinforced polymer (GFRP) specimens for detection of subsurface hidden defects using pulse compression favourable thermal wave imaging techniques. [10 ], by Kher and Mulaveesala, explores the defect detection probability of pulse compression favourable thermal excitation schemes for infra-red non-destructive testing, whereas Derusova et al. evaluates impact damage in Kevlar/carbon composites using laser vibrometry and active infrared thermography in [11 ]. [12 ], by Siddiqui et al., proposes a numerical study on the applicability of P4 codes-based pulse compression favourable thermal wave imaging approach for thermal NDT, while Ahmad et al. study the applicability of Barker coded independent component thermography for testing and evaluation of deep subsurface defects in steel sample in [13 ]. In [14 ], Sharma et al. propose an analytical approach for examining of the severity of osteoporosis using linear frequency modulated thermal wave imaging, and in [15 ] Das and Kundu estimate the magnetic field strength in a porous fin from a surface temperature response. Optical NDT [16 ], by Majumder, Gupta and Dubey, demonstrates compressive sensing-based single-pixel camera architecture to acquire spectral images that can be used for non-destructive testing and classification of explosive materials. Electrical NDT [17 ], by Jiuhao Ge et al., demonstrates a wavelet packet energy-based algorithm proposed to classify surface and non-surface slits through the pulsed alternating current field measurement technique. Ultrasonic NDT [18 ], by Maheshwari et al., presents hollow cone attachments coupled with conventional ultrasonic transducers for achieving subwavelength resolution imaging at a relatively higher speed and minimal cost, while Kumar, Shakya and Goswami demonstrate the optimal frequency combination estimation for accurate ultrasound non-destructive testing for an object with a heterogeneous inner profile in [19 ]. In [20 ], Sikundalapuram et al., present an elastic metamaterial rod for mode filtering in ultrasonic applications. Finally, in [21 ], Lee et al. study a six-axis robot arm to develop a robotic scanning algorithm which can be applied to the laser pulse-echo inspection of non-flat objects. Summary/Conclusion This Special Issue aims to demonstrate the breadth of applications for which one can use non-destructive testing techniques, together with very recent research developments and some of the necessary background theory that underpins the basic NDT testing techniques.
