2-2.4 GHz Meta-Absorber Design
Budget: ₹1,500 – ₹12,500 INR
This project centres on a metamaterial absorber that will operate between 2 GHz and 2.4 GHz for a telecommunications platform. I am using Rogers 4350B with a 1.524 mm thickness, so every simulation and layout must respect that specific substrate stack-up. The finished surface should maintain more than 92 % absorption across the entire band while remaining both angle and polarization insensitive; incidence from 0 ° up to 60 °—for TE and TM, normal as well as oblique—has to meet the same performance target.
Because the unit will be installed in a coastal environment, the design must tolerate sustained high humidity without performance drift. A manually adjustable feature is required; a simple, reliable way to trim or retune the absorber after fabrication (for example by replaceable lumped elements, screw-tuned posts, or similar low-complexity means) will satisfy this need as long as the adjustment range preserves the key specs.
Please base the work on full-wave EM simulation (CST Microwave Studio, HFSS, or an equivalent recognised tool) and provide:
• 3-D model and project files for all simulations
• S-parameter, absorption, and angular-sweep plots demonstrating the > 92 % target for both polarizations
• Gerber or DXF layers ready for PCB manufacture, plus a concise fabrication note covering the humidity-resistant finish you recommend
• A short tuning guide explaining the manual adjustment procedure and its expected effect on resonance
Testing or measurement plans are welcome if you have lab access, but validated simulation backed by clear documentation will be the primary acceptance criterion.
