Massive MIMO is a promising technology for next generation cellular networks.

An AlGaN/GaN based field effect transistor (FET) has been designed, fabricated, and used as a resistive mixer for heterodyne detection in the 140-220 GHz frequency range.

Higher capacity wireless access networks are required to serve the growing demands for mobile traffic and multimedia services.

We demonstrate a sub-wavelength spherical resonator at microwave frequencies designed to mimic the electromagnetic behavior of a negative permittivity sphere.

A multiple exposure technique is used to print various types of patterns with critical dimensions much smaller than the wavelength of light used for exposure.

Most talker verification systems make use of talker models based on analysis of whole words or phrases.

A new filter architecture is proposed which employs optical half-band and allpass filters but circumvents the typical tradeoff between passband width and peak delay inherent to allpass filters.

This paper presents a new LPC parameter quantization method - SubBand Synthesized LPC Vector Quantization (SBS-LPC-VQ).

We report cyclotron resonance measurements on GaInAs-AlInAs heterojunctions in which two electrical subbands are occupied in magnetic fields with components both perpendicular and parallel to the i

Scanned zone melt recrystallization (ZMR) of amorphous Si 1micron films on SiO sub 2 results in subboundary-free material provided the thermal gradient along the scan is reduced to 4 K/mm or less.
