A Compact Uniplanar Electromagnetic Bandgap Structure with Wide Bandgap
2021 IEEE 19th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2021This paper presents a new compact uniplanar electromagnetic bandgap (EBG) structure for K band applications. The proposed unit cell consists of corner square patches which are connected at the center by meander lines and interdigital capacitors (IDC) along the edges.

A digital bandgap reference that provides a programmable reference voltage output is presented. It uses the same idea as an analog bandgap circuit except that the three operations of differencing, scaling and addition are done in the digital domain after converting the operands, the analog junction-diode voltages, into numbers.

Extending bandgap of air-core photonic bandgap fibers
SPIE Proceedings, 2010Air-core photonic bandgap fibers offer many unique properties and are critical to many emerging applications. A notable property is the high nonlinear threshold which is the key for applications at high peak powers. The strong interaction of light and air is also essential for a number of emerging applications, especially those based on nonlinear ...

Bandgap splitting in liquid crystal photonic bandgap fibers
OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008The polarization dependent bandgap splitting for nematic liquid crystal photonic bandgap fibers (LCPBGFs) is investigated. We proposed two orthogonal polarization dependent bandgap for guiding linear-polarized fiber modes of LCPBGFs.

Comparison of the electrochemical and optical bandgap of low-bandgap polymers
Synthetic Metals, 2003The use of low bandgap polymers in organic photovoltaics for better light harvesting is getting more and more important. For determination of the electrochemical bandgap cyclovoltammetry (CV) and electrochemical voltage spectroscopy (EVS) was applied. The optical bandgap was determined by optical absorption measurements.
