Sinusoidal plane-wave solutions of the electromagnetic wave

November 25, 2011

Sinusoidal plane-wave solutions are particular solutions to the electromagnetic wave equation.The general solution of the electromagnetic wave equation in homogeneous, linear, time-independent media can be written as a linear superposition of plane-waves of different frequencies and polarizations.

Honeywell and Sinochem Announce Formation of Joint Venture

November 24, 2011

Honeywell (NYSE: HON) and Sinochem Group announced today they have signed an agreement to form a 50/50 joint venture to produce and sell blowing agents for energy efficient foam insulation in China to meet growing demand in the Asia region for more energy efficient and environmentally friendlier materials. The formation of the joint venture is subject to Chinese government approval.

PPP Configuration Options

November 24, 2011

The previous section introduced the use of LCP options to meet specific WAN connection requirements. PPP may include the following LCP options: Authentication - Peer routers exchange authentication messages. Two authentication choices are Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP).

PPP and tunnels

November 24, 2011

Many protocols can be used to tunnel data over IP networks. Some of them, like SSL, SSH, or L2TP create virtual network interfaces and give the impression a direct physical connections between the tunnel endpoints. On a Linux host for example, these interfaces would be called tun0.

Electromagnetic radiation

November 24, 2011

Electromagnetic radiation (often abbreviated E-M radiation or EMR) is a form of energy that exhibits wave-like behavior as it travels through space. EMR has both electric and magnetic field components, which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation.

The physics of electromagnetic radiation

November 24, 2011

The physics of electromagnetic radiation is electrodynamics. Electromagnetism is the physical phenomenon associated with the theory of electrodynamics. Electric and magnetic fields obey the properties of superposition. Thus, a field due to any particular particle or time-varying electric or magnetic field contributes to the fields present in the same space due to other causes.
