Reversible multilayered vesicle-like structures with fluid hydrophobic and interpolyelectrolyte layers

Multilayered Amorphous Silicon Structures

Spherical cloaking with homogeneous isotropic multilayered structures.

We propose a practical realization of electromagnetic spherical cloaking by layered structure of homogeneous isotropic materials. By mimicking the classic anisotropic cloak by many alternating thin layers of isotropic dielectrics, the permittivity and permeability in each isotropic layer can be properly determined by effective medium theory in order to achieve invisibility. The model greatly fa...

Spontaneous and reversible switch from amphiphilic to oil-like structures.

Current theories assume that the amphiphilicity of biological membranes is always preserved. We observed that two hydrogen-bonding lipid layers in contact can spontaneously and reversibly lose their amphiphilic structure and turn into an assembly of oily complexes. This result opens a new angle for understanding the reorganization of lipids during membrane fusion, since similar complexes could ...

Theory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures

A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...

Improving Subwavelength Resolution of Multilayered Structures Containing Negative-permittivity Layers by Flatting the Transmission Curves

Multilayered structures consisting of alternating negativepermittivity and dielectric layers are explored to obtain high-resolution imaging of subwavelength objects. The peaks with the smallest |ky| (ky is the transverse wave vector) on the transmission curves, which come from the guided modes of the multilayered structures, can not be completely damped by material loss. This makes the amplitud...
