Electromagnetic Field Tapering in the High-Roughness Substrates Coated by a Thin Film of Manganese: A Lithography-Free Approach to Ultra-Broadband, Wide-Angle, UV to FIR Perfect Absorption
Majid Aalizadeh, Mohammad Reza Tavakol, Amin Khavasi +2
Metallic layers are known to be used for the suppression of wave transmission when their thickness is sufficiently higher than the skin depth of metal. If in addition to blocking t…
Designing Dual-Band Absorbers by Graphene/Metallic Metasurfaces
Saeedeh Barzegar-Parizi, Amin Khavasi
This article presents a novel approach for designing dual-band absorbers based on graphene and metallic metasurfaces for terahertz and mid-infrared regimes, respectively. The absor…
A Route to Unusually Broadband Absorption Spanning from Visible to Mid-Infrared
Majid Aalizadeh, Amin Khavasi, Andriy E. Serebryannikov +2
In this paper, a route to ultra-broadband absorption is suggested and demonstrated by a feasible design. The high absorption regime (absorption above 90%) for the suggested structu…
Lithography-Free, Manganese-Based Ultra-Broadband Absorption Through Annealing-Based Deformation of Thin Layers into metal-air composites
Majid Aalizadeh, Amin Khavasi, Bayram Butun +1
Fabrication, characterization, and analysis of an ultra-broadband lithography-free absorber is presented. An over 94% average absorption is experimentally achieved in the wavelengt…
Wideband Antireflection Coating Using Metamaterials
Fahimeh Sepehripour, Parisa Karimi, Amin Khavasi
In this paper, we propose a new approach for realizing antireflection coating using metamaterials. In this approach, a subwavelength array of metallic pillars (with square cross-se…
