This paper proposes a near-optimal procedure to localize a single stationary source in a two-path underwater acoustic environment.

In this paper, we present a low complexity detection algorithm for Multiple-Input Multiple-Output (MIMO) systems.

We image in near-field the transverse modes of semiconductor distributed feedback (DFB) lasers operating at lambda approximate to 1.3 mu m and employing metallic gratings.

A near-field probe fabrication technique for far infrared frequencies based on photoconducting antennas is developed.

A near-field probe fabrication technique for far infrared frequencies based on photoconducting antennas is developed.

We present phase-sensitive, high spatial resolution, near-field microwave microscopy images of the rf fields radiated by piezoelectric resonators operating in the vicinity of 2GHz.

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.
