Web14 apr. 2011 · While the word ‘hemispherical’ is used to describe the variation, the inner core is not divided into two equal halves. Rather, the inner core is divided into two segments, by two lines of constant longitude which are not necessarily separated by 180°: suggestions of the separation of the two longitudes range from 120° to 170°. WebIt is a fundamental property of antennas that the receiving pattern (sensitivity as a function of direction) of an antenna when used for receiving is identical to the far-field radiation …

Hemispherical attenuation coefficient: μ: m −1: Radiant flux absorbed and scattered by a volume per unit length, divided by that received by that volume. Spectral hemispherical attenuation coefficient: μ ν or μ λ: m −1: Spectral radiant flux absorbed and scattered by a volume per unit length, … Meer weergeven The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the … Meer weergeven Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give diffuse reflection. For specular surfaces, such as glass or polished metal, reflectance is nearly zero at all angles … Meer weergeven The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.
