Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...

Analytical theory of extraordinary optical transmission through realistic metallic screens
(Optical Society of America, 2010)
An analytical theory of extraordinary optical transmission (EOT) through realistic metallic screens perforated by a periodic array of subwavelength holes is presented. The theory is based on our previous work on EOT ...

SMASH ΔΣ modulator with adderless feed-forward loop filter
(Wiley-Blackwell, 2017)
A novel cascade ΔΣ modulator, which combines the benefits of sturdy MASH (SMASH) topology and feed-forward loop filter, is presented. The proposed ΔΣ architecture is based on moving the power-hungry adder block from the ...

Digital VLSI Implementation of Piecewise-Affine Controllers Based on Lattice Approach
(Institute of Electrical and Electronics Engineers, 2015)
This paper presents a small, fast, low-power consumption solution for piecewise-affine (PWA) controllers. To achieve this goal, a digital architecture for very-large-scale integration (VLSI) circuits is proposed. The ...
