Determination of physical properties of concrete by using microwave nondestructive techniques
(Applied Computational Electromagnetics Society (ACES), 2018)
Determination of the electrical properties of concretes with different water/cement ratios and investigation of the relationship between their electrical and mechanical properties is a promising technique towards improving ...
Artificial neural network approach for locomotive maintenance by monitoring dielectric properties of engine lubricant
In this paper, we proposed an approach for locomotive maintenance systems by observing engine lube oil. The mechanical particles in lube oil give information about locomotive engine system condition. The engine lubricant ...
A Nondestructive Method for Determining Fiber Content and Fiber Ratio in Concretes Using a Metamaterial Sensor Based on a V-Shaped Resonator
A micro sensor based on a V-shaped resonator (VSR) is implemented for the purpose of determining fiber content and ratio in construction materials as a nondestructive method. Concrete is investigated as the construction ...
Metamaterial Sensor for Transformer Oil, and Microfluidics
(Applied Computational Electromagnetics Society (ACES), 2019)
Metamaterial sensor which is composed of split square rings to operate in X band for liquid and microfluidics has been proposed in this study. For measurement and simulation, we have designed and manufactured a sample ...
Investigation of microwave power limiter for Industrial Scientific Medical band (ISM) applications
In this paper, a new design of microstrip power limiter which is based on microstrip technology and zero bias Schottky diode is introduced. In this context, the FR-4 substrate that was characterized by dielectric permittivity ...
A Split Meander Line Resonator-Based Permittivity and Thickness Sensor Design for Dielectric Materials with Flat Surface
A metamaterial-based permittivity and thickness sensor structure for dielectric substrate material has been proposed at the X band frequency regime. The sensor structure is designed by using a split meander line type ...
