We’re excited to share that the latest research from the POLYNICES project has just been published in IEEE Transactions on Microwave Theory and Techniques!
The publication is entitled “Microstructured Water-Based Broadband Terahertz Pyramidal Absorber” and it is authored by Kalliopi Spanidou, Daniel Headland, Sharath Sriram, Itziar Maestrojuán Biurrun and Guillermo Carpintero.
This study presents a novel pyramidal terahertz absorber, combining the high loss properties of liquid water with the microscale precision of UV-cured 3D printing. The result is a powerful, compact, and cost-effective absorber with:
✅ Over 99% absorption in the 75–190 GHz range
✅ 99.99% absorption from 190–500 GHz
✅ Simulated performance up to 1000 GHz with absorption exceeding 99.999%
These findings pave the way for scalable absorbers in next-generation 5G/6G wireless systems, radar, and sensing — aligning closely with POLYNICES’ mission to advance photonic integration for high-frequency applications.
Congratulations to all authors and collaborators involved!
