Intorduction:

The aim of this project is to design soil moisture sensors based on harmonic radar principle. The project designs a novel harmonic radar prototype based on second harmonic detection with respect to the property of material. Initially the design will be done on commercially available substrates and later extended to bio-based materials for eco-friendly design. Various parametric analysis will be done and optimised during the design phase. The sensors will be designed using commercially available electromagnetic simulation software (Ansys HFSS).The designed prototype will be fabricated and tested in real scenarios which requires soil moisture identification.

Description:

Student tasks would by to simulate a novel radiating design having prominent harmonic radiation on Ansys HFSS software with acceptable reflection and radiation properties on a selected material. This includes

• Design of radiating prototype on conventional low loss materials.
• Extension of the design to biodegradable materials if possible with acceptable radiation properties.
• Optimisation of the design for moisture sensing applications

Requirements:

• We are looking for talented and open-minded students who have a background and interest in electrical engineering, material engineering, or other relevant areas.
• Students should have strong interest in microwave design.
• Knowledge of EM simulation software is welcome but not mandatory.
