The presence of multipath effects in terahertz wireless links degrades signal quality, making absorbers a critical component of 5G/6G wireless systems. Here, we leverage the innately high loss of liquid water, combined with the microscale precision of UV-cured resin-based micro 3-D printing, to realize a viable pyramidal absorber for terahertz waves. Both simulation and experimental results confirm near-unity absorption, achieving over 99% in the 75–190 GHz range and 99.99% over 190–500 GHz. Furthermore, simulations show that the absorber maintains high performance up to 1000 GHz, with absorption exceeding 99.999%. These results demonstrate potential for future micro 3-D-printed resin-based absorbers that can be readily tailored to serve in communication, sensing, and radar applications, thanks to their microscale size, cost-effectiveness, and adaptability to broadband terahertz wireless systems.
期刊介绍:
The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
