A dear-sky spectral solar radiation model for direct and diffuse fluxes, combined with topographic calculations from digital terrain data, computes either incident, net, or reflected solar radiation at any point on a snow surface in mountainous terrain. The radiation may be integrated over any wavelength range from 250 to 5000 nm, or over any time step. Atmospheric attenuation parameters are oz...
In developing countries like Nepal, the direct measurement of global solar radiation (GSR) is difficult. So, estimation GSR carried out at Jumla (29°16′ N, 82° 11′ E and about 2347 m altitude) for year 2015 2017 using regression technique to meteorological parameters on Angstrom model, Gopinathan Olomiyesan- Oyedum models. Among three models, Olomiyesan model better than other Its empirical con...
Electromagnetic properties depend on the composition of materials, i.e. either angstrom scales of molecules or, for metamaterials, subwavelength periodic structures. Each material behaves differently in accordance with the frequency of an incoming electromagnetic wave due to the frequency dispersion or the resonance of the periodic structures. This indicates that if the frequency is fixed, the ...
