A key test index is the p-value (called χ 2-probability in Barlow, 1989, p. 150) defined as the probability that the value of χ 2 is larger than calculated under the hypothesis that the xi are a random realization of PDF. ∞ p-value = χk2(s)ds χ2 where χ 2 is the value...
Among these, the polarization- division-multiplexing (PDM) scheme, which supports two independent data channels on a single wavelength with orthogonal polar- ization states, has become a standard one in most state-of-art telecommunication systems. Currently, however, only two polarization states (...
With the FKM sample, both components of the terahertz time-domain waveforms are shifted com- pared with those obtained without the samples because of the refractive index of the samples. In addition, the Scientific Reports | 6:39079 | DOI: 10.1038/srep39079 3 www.nature.com/scientificreports/...
12、ngsstrecken - Messung der Polarisationsmodendispersion von installierten bertragungsstrecken (IEC 61280-4-4:2006) This European Standard was approved by CENELEC on 2006-02-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for givin...
Broadband MM linear converters have been demonstrated in the short-wavelength infrared band by using high-refractive-index silicon cut-wire structure28. MMs-based polarimetric devices are particularly attractive in the microwave frequency range due to the lack of suitable nat- ural materials for ...
