A near-field scanning optical microscope (NSOM) is used in transmission to study the anisotropic stress variations in SiN membranes, nominally 50 nm thick, containing arrays of submicron size holes
By use of a near-field scanning optical microscope (NSOM) in collection mode, the intensity distribution along a 2 X 2 multimode interference coupler was directly imaged as a function of wavelength
Probing optical properties of materials and optical characterization of crystallographic defects at the nanometer scale have been inaccessible until recently due to the diffraction limit of light.
We demonstrate near-ideal lateral scaling in abrupt junction Al sub (0.48) In sub (0.52) As/In sub (0.53) Ga sub (0.47) As heterostructure bipolar transistors.
Strong and direct near-infrared intersubband absorption is observed at room-temperature in silicon-doped lattice-matched InAlN/GaN superlattices grown by molecular beam epitaxy on GaN templates gro
Strong near-infrared intersubband absorption is observed directly at room temperature in silicon-doped lattice-matched InAlN/GaN superlattices grown by molecular-beam epitaxy on GaN templates grown
We study the approximability of two classes of network routing problems.
Using cyclic prefix (CP), the transmission schemes, Orthogonal frequency-division multiplexing (OFDM), Single carrier block transmission, and Time Reversal, can be unified as linear block precoding
A practical distributed Gaussâ"Newton method for the near-optimal computation of interference alignment solutions is proposed, based on the block-wise structure of Jacobian matrix of the residual
We introduce a discrete network corresponding to any Gaussian wireless network that is obtained by simply quantizing the received signals and restricting the transmitted signals to a finite precisi
