Holographic Microwave Imaging for Biomedical Applications and Non-Destructive Testing

We are interested in developing novel 2D and 3D holographic microwave imaging algorithms. These techniques are fast and very robust to noise. They rely on the measurement of the scattered field on the rectangular or cylindrical apertures.

Water Quality Testing with Microwave Sensors

We are developing microwave sensors for testing the quality of water. The microwave sensors need to have high-quality factors to be able to sense trace amounts of pollutants in water. Using an array of microwave sensors resonating at different frequencies and applying machine learning to the acquired responses significantly improves the specificity of the detection of the pollutants.

Antennas for Wireless Communications (e.g., MIMO Applications)  

We are interested in the design, fabrication, and measurement of novel multi-band MIMO antennas with radiating elements suitable for long-term evolution (LTE) and wireless fidelity (Wi-Fi) applications in handheld devices. We characterize the antennas in free-space as well as in the proximity of the user head and hand.

Electromagnetic Non-Destructive Testing (Magnetic Flux Leakage Technique, Eddy Current Technique, Microwave/Millimeter Wave Imaging)

We are interested in electromagnetic nondestructive testing techniques for inspection of metallic structures (MFL technique, Eddy current technique, and ACFM technique). This includes providing simulation models for the responses obtained in the relevant techniques and proposing novel inversion techniques such as space mapping optimization to estimate the shape parameters of the defects.

Wireless Sensing of Soil Quality

We are working on wireless soil quality testing systems. In our developed system, passive sensors can be embedded inside the soil and ground penetration radars (GPRs) can be employed to measure the response of embedded sensors. To separate the response of the sensor from the interferences, a surface acoustic wave (SAW) device is utilized.
