A Direction-Sensitive Microwave Sensor for Metal Crack Detection
نویسندگان
چکیده
For metal crack nondestructive detection, most conventional sensors are unable to realize the direction detection. In this work, a direction-sensitive microwave sensor is proposed for The consists of rectangular patch resonator and two perpendicular coupled feeding ports, which improves current distribution on surface sensitivity performances verified by simulation measurement experiments. results show that width sensitivities ports 100 MHz/mm 63.3 MHz/mm, respectively, detection 6.10 MHz/5 degrees 1.93 degrees, respectively. Due advantages simple structure, low profile, large coverage area high sensitivity, has great application potential in fields.

A Circular Microstrip Antenna Sensor for Direction Sensitive Strain Evaluation †
In this paper, a circular microstrip antenna for stress evaluation is studied. This kind of microstrip sensor can be utilized in structural health monitoring systems. Reflection coefficient S11 is measured to determine deformation/strain value. The proposed sensor is adhesively connected to the studied sample. Applied strain causes a change in patch geometry and influences current distribution ...

This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...
متن کاملA Sensitive Sensor for Nano-Molar Detection of 5-Fluorouracil by Modifying a Paste Sensor with Graphene Quantum Dots and an Ionic Liquid
5-fluorouracil is a widely used anticancer drug with many side effects on humans, and hence its analysis in biological samples is very important. Accordingly, a novel sensitive electrochemical approach was fabricated by incorporating graphene quantum dots (GCD) and 1-butylpyridinium bromide (BPBr) in the formulation of a carbon paste electrode (GQD/BPBr/CPE). The GQD was synthesized and charact...
