Multifunction wideband polarization converting metasurface for microwave band application
Project Area of Specialization Information & Communication TechnologyProject SummaryConventional techniques using the Faraday Effect and optical activity of crystals can be used for polarization control, but the limitations associated with these techniques such as bulky size, narrow bandwidth, and incidence angle-dependent response make them incompatible for many practical applications.
In stealth technology, a key objective is to reduce the radar cross-section (RCS) of metallic objects such as missiles and aircraft. In the past, many metasurfaces have been designed on it. But the most common drawbacks are narrow bandwidth, thick in size, increased weight, and costly which limited their application. Thus, the design of a wide Band RCS reduction with high efficiency is still a challenging task.

- Fabrication of the designs mentioned in the activity at S.NO. 1 and 2.
- Testing of the designs mentioned in the activity at S.NO. 1 and 2.
- Thesis and research papers write-up.
Methodology for Implementation of Project
To design the multifunctional wideband Polarization Converting metasurfaces for microwave application, computer simulation technology (CST) microwave studio (2020) software will be used and substrate material for proposed metasurfaces will be F4BM with ?r=2.2. For unit cell and the ground will be used good conductor material. The fabrication will be done in China after the simulation.
Benefits of the ProjectUtilization of Project Results: The following are the major features of the metasurface that make it suitable for real-world applications, high efficiency, ultrawide bandwidth, the simple structure having a minimal thickness, lightweight, and relaxed fabrication. Because of this feature, the PCM has the potential can be used in different applications where polarization conversion devices are needed.
The proposed metasurface will be utilized in different areas, some of them are given below;
- Satellite communication
- Stealth Technology
- Defense System
- Air born
- Marine
- Surveillances
- Invisibility
- Antenna design (gain and bandwidth enhancement).
- Radar cross section reduction.
The proposed MS is validated experimentally. Experimental results are found in good concurrence with simulations.
