'Nanocamera' takes pictures at distances smaller than light's own wavelength

July 17, 2014 6:40 pm | by EurekAlert! | News | Comments

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light). A standard optical microscope acts as a "nanocamera" whereas the pBNAs are the analogous film.

Plasmon-enhanced Polarization-selective filter

July 17, 2014 1:54 pm | by EurekAlert! | News | Comments

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer is also called half-wave plate, which constructed out of a birefringent material (such as quartz or mica).

How to drive LEDs with power factor correction in a single stage

July 16, 2014 1:47 pm | by Brian King, Texas Instruments, www.ti.com | Texas Instruments | Blogs | Comments

A PFC-SEPIC converter can be controlled using a traditional PFC-boost controller. An important characteristic of the SEPIC is the lack of isolation.  This limits the use of this topology to applications that don’t require safety isolation.  Think about applications that are completely sealed with no user-accessible energized parts, like street lights and high-bay lighting.
