In recent few years, the antenna and sensor communities have witnessed a considerable
integration of radio frequency identification (RFID) tag antennas and sensors because of the …

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; …

Integrity assessment of metallic structures requires inspection tools capable of detecting and
evaluating cracks reliably. To this end, many microwave and millimeter-wave nondestructive …

This paper presents a highly sensitive sensor for crack detection in metallic surfaces. The
sensor is inspired by complementary split-ring resonators which have dimensions much …

Crack detection is an important step in assessing the quality of pressed panel products. This
paper presents a fast and non-invasive crack detection technique which involves extracting …

Antennas embedded in composites are key components in communication, radar, and
sensing systems aboard aircrafts. The manufacturing complexities and in-service loading …

A novel design of a thin isotropic frequency-selective surface (FSS) composed of a
subwavelength electromagnetic metamaterial structure is proposed and its application as …

Imaging probes which work at relatively low microwave frequencies in the ultrahigh
frequency band (UHF) facilitate imaging through high loss dielectric materials and yield …

Microwave testing can detect surface and sub-surface flaws and anomalies under coatings,
paint, or dirt in metallic structures. A major application of microwave sensors with an …

Various near-field microwave imaging probes were developed previously for nondestructive
testing of material structures. Sensitivity and resolution are key parameters for quantifying …
