Byusingadoubleperturbationmethodwhichassumesthatbothε andμaresmall,we approximate analytical conditions for the existence and bifurcation of nonlinear quasiperiodic motions in the neighborhood of the ...
We investigate the dynamics of a delayed nonlinear Mathieu equation:¨ x + (δ + εα cost)x + εγx 3 = εβx(t − T) in the neighborhood of δ = 1/4. Three different phe-nomena are combined in this syst...
This work concerns linear parametrically excited systems that involve multiple resonances. The property of such systems is that if the parameters are fixed and lie inside a resonance tongue, the motio...
We investigate a phenomenon observed in systems of the form dx/dt = a 1 (t)x+a 2 (t)y,dy/dt = a 3 (t)x+a 4 (t)y,where a i (t) = P i + ε Q i cos2t, where P i ,Q i and ε are given constants,and where it...
We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain ...
Ground response analyses are mostly used for the development of design response spectra in the modern earthquake engineering. After 1999 Marmara Earthquake, the damages were mostly related with unav...
FAYETTEVILLE, Ark. – An international team of scientists predicts that a phenomenon known in physics as Fano resonance can exist in materials that are used in electronic devices.
We numerically demonstrate total absorption in graphene in the near-infrared and visible wavelength ranges by means of critical coupling with guided resonances of a photonic crystal slab. In this wave...
Fano resonances with a characteristic asymmetric line shape can be observed in light scattering, transmission and reection spectra of resonant optical systems1.
Reflection occurs at an air–material interface. The development of antireflection schemes, which aims to cancel such reflection, is important for a wide variety of applications including solar cells a...
We report ultra-compact surface-normal high-Q optical filters based on single- and double-layer stacked Fano resonance photonic crystal slabs on both Si and quartz substrates. A single layer photonic ...
We present here ultra-compact high-Q Fano resonance filters with displaced lattices between two coupled photonic crystal slabs, fabricated with crystalline silicon nanomembrane transfer printing...
We show how to calculate the first- and second-order statistics of the scattered fields for an arbitrary intensity coherent-state light field interacting with a two-level system in a...
We develop a temporal coupled-mode theory to describe the interaction of plane wave with an individual scatterer having an arbitrary shape. The theory involves the expansion of the fields on cyl...
