Encoding Information with Light’s Orbital Angular Momentum Light is the future of communication‚ traveling at 3‚000‚000 meters per second‚ the cosmic speed limit of the universe. Its tremendous speed makes it optimal for data transmission. The conventional method to encode information in light is through amplitude modulation‚ i.e. light pulses‚ time division multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel

Of course‚ the majority of mankind cannot use the Internet nowadays or in the near future‚ since they live in countries which lack the necessary economical and technological infrastructure. But the Internet causes polarization in developed countries‚ too: people are divided into Internet users and Internet illiterates‚ and as the use of the Internet grows and often replaces traditional methods of communication‚ the illiterates may find themselves in an awkward position

2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface

interfacial polarization‚ which is in agreement with Koops phenomenological theory [36]. The large values of dielectric constant at lower frequencies may be explained on the basis of space charge polarization due to inhomogeneities present in dielectric structure‚ viz. porosity and grain boundary for the present ferrite and ferroelectric system. This may be attributed to the dipoles resulting from changes in valence states of cations and space charge polarization. The space charge polarization is governed

MD SAEED ANWAR SOCIOLOGY DISCIPLINE KHULNA UNIVERSITY Introduction Political science and sociology began to develop as independent disciplines in the nineteenth century under the influence of marginalist economics which attempted to demarcate the study of the ‘political’ from that of the ‘social’ and the ‘economic’ Political sociology broadly conceived is the study of power and domination in social relationships. It could thereby include analysis of the family‚ the mass media‚ universities‚ trade

In this case‚ the chart titled‚ “Party Polarization‚ 1879-2010: Ideological Gap Between the Parties” highlighted the differences between the Republicans and the Democrats in both the House and the Senate (Mann and Ornstein 45). During the Gilded Age to near the beginning of the Great Depression‚ the difference was high between the Republican and the Democrats. It is interesting to note that during the FDR era‚ the polarization was lower but immediately crept higher afterwards. However
