Journal ArticleDOI
Design and analysis of perfect terahertz metamaterial absorber by a novel dynamic circuit model
TL;DR: A quasistatic dynamic circuit model can decently describe operational principle of metamaterial terahertz absorbers based on interference theory of reflected waves and the effect of changing in spacer thickness and metal conductivity on absorption spectrum is analyzed.
Journal ArticleDOI
Polarization-Dependent, Frequency-Selective THz Stereometamaterial Perfect Absorber
TL;DR: In this article, a terahertz material constructed from geometrically placed copper rings acts as a perfect absorber and exhibits rotationally asymmetric absorption behavior, which is similar to chiral molecules found in nature.
Journal ArticleDOI
Equivalent-Circuit Interpretation of the Polarization Insensitive Performance of THz Metamaterial Absorbers
TL;DR: In this article, a metamaterial perfect absorber was investigated through finite element numerical method and a new equivalent-circuit electric model was proposed to interpret this polarization insensitivity.
Journal ArticleDOI
Atom Probe Tomography of Zinc Oxide Nanowires
Nabil Dawahre,Gang Shen,Soner Balci,William Baughman,David S. Wilbert,Nicholas Harris,Lee Butler,R. L. Martens,Seongsin M. Kim,Patrick Kung +9 more
TL;DR: In this article, the growth of well-aligned single-crystal ZnO nanowire arrays on sapphire substrates by chemical vapor deposition and the development of atom probe tomography was reported.
Journal ArticleDOI
Investigation of robust flexible conformal THz perfect metamaterial absorber
Ju-Hyung Kim,Mohammad Parvinnezhad Hokmabadi,Soner Balci,Elmer Rivera,David S. Wilbert,Patrick Kung,Seongsin M. Kim +6 more
TL;DR: In this paper, a flexible metamaterial absorber was designed and simulated such that absorbers exhibited two distinct resonance frequencies with the strength of absorption for both sensitive to the center-to-center spacing of the rings and polarization.
