Step-by-step design and optimization of a broadband MIM absorber is presented, geometrically and in terms of materials. The important advantage of this absorber is the use of three large area layers without any need to lithography or any repetition of MI pairs, which makes this absorber as sim...

(MI) stacks fabricated employing straightforward layer deposition techniques and are, therefore, lithography-free and large-scale compatible. We scrutinize the impact of different physical parameters of an MIMI absorber structure with analysis of each contributing metal layer. After obtaining the optimal ...

The average sound-absorption coefficient of an ultra-broadband parallel sound absorber, between 0 and 2000 Hz, is optimized in certain conditions. This is accomplished using a teaching–learning-based optimization algorithm, where the geometric parameters are used as optimization variables. The optimized...
metallic phase (e.g., by raising the operating temperature above ~341K), the loss factor of the unit cell will be enhanced, and in this case with the assistance of multi-mode resonances, the metasurface will turn into a perfect broadband circular-polarization-insensitive EM absorber. Based ...
Research on terahertz waveguides is experiencing a tremendous growth due to their importance for compact and robust THz systems. However, designing compact, broadband, mechanically stable and environmentally shielded THz waveguides is still a challenge d
We demonstrate that adding a thin layer of a suitable absorber, here exemplified with water, the dispersion can be even further reduced (jb2j , 1 ps/THz/cm in the 0.3–1 THz range), without increasing the overall loss. The absorptive cladding is also effective for reducing the bend loss...
