Multiple issues refimprove July 2011 orphan July 2011 context July 2011 In computation of radiation performance of multi port antennas especially in multiple input multiple output MIMO antenna systems total active reflection coefficient, TARC, relates the total incident Electric power power to the radiated Transmitter power output power . The total active reflection coefficient TARC is the square root of the sum of all incident powers at the ports minus radiated power, divided by the sum of all incident powers at the ports of an N port antenna. The TARC is a function of frequency . With this definition we can characterize the multi port Antenna radio antenna s frequency Bandwidth signal processing bandwidth and radiation performance. TARC can be computed directly from the scattering matrix for different excitations. math Gamma t a frac sqrt sum i 1 N b i 2 sqrt sum i 1 N a i 2 . math where math b S a . math math S math is the antenna s scattering matrix , math a math is the excitation Euclidean vector vector , and math b math represents the scattered vector. The TARC is a real number between zero and one. When the value of the TARC is equal to zero, all the delivered power is radiated and when it is equal to one, all the delivered power is either reflected back to sources or goes to the other ports.

Unreferenced date March 2007 Signal reflection occurs when a signal is transmitted along a transmission medium, such as a reflections on copper lines copper cable or an optical fiber . Some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This happens because imperfections in the cable cause Electrical impedance impedance mismatches and non linear changes in the cable characteristics. These abrupt changes in characteristics cause some of the transmitted signal to be reflected. In radio frequency RF practice, this is often measured in a dimensionless ratio known as voltage standing wave ratio VSWR with a VSWR bridge. The ratio of energy bounced back depends on the Impedance matching impedance mismatch . Mathematically, it is defined using the reflectioncoefficient . Because the principles are the same, this concept is perhaps easiest to understand when considering an optical fiber. Imperfections in the glass create mirrors that reflect the light back along the fiber. Impedance discontinuities cause attenuation , attenuation distortion , standing waves , ringing signal ringing and other effects because a portion of a transmitted signal will be reflected back to the transmitter transmitting device rather than continuing to the receiver radio receiver , much like an echo. This effect is compounded if multiple discontinuities cause additional portions of the remaining signal to be reflected back to the transmitter. This is a fundamental problem with the daisy chain electrical engineering daisy chain method of connecting electronic components.

Unreferenced date December 2009 In Euclidean geometry , oblique reflections generalize ordinary reflection mathematics reflections by not requiring that reflection be done using perpendicular s. If two points are oblique reflections of each other, they will still stay so under affine transformation s. Consider a plane geometry plane P in the three dimensional Euclidean space . The usual reflection of a point A in space in respect to the plane P is another point B in space, such that the midpoint of the segment AB is in the plane, and AB is perpendicular to the plane. For an oblique reflection , one requires instead of perpendicularity that AB be parallel to a given reference line. Formally, let there be a plane P in the three dimensional space, and a line L in space not parallel to P . To obtain the oblique reflection of a point A in space in respect to the plane P , one draws through A a line parallel to L , and lets the oblique reflection of A be the point B on that line on the other side of the plane such that the midpoint of AB is in P . If the reference line L is perpendicular to the plane, one obtains the usual reflection. For example, consider the plane P to be the xy plane, that is, the plane given by the equation z 0 in Cartesian coordinates .
