... 200 ohms. Normally, we use 200 ohms in order to make use of a 4:1 splitter balun to match to a 50ohm feed cable. There are cases, however, where no balun can be used, due to either high voltages or a lack of space. The Para-IRA is an example of such a case. In these cases, there is no reason to conf ...

... High-temperature superconductivity in copper oxide compounds has been viewed as an “exotic” phenomenon since its discovery in 1986. It was suggested that superconductivity in the cuprates is driven by magnetic interactions between carriers or by polaron formation rather than by the conventional mech ...

... We see that if c2 < c1 , R is negative; that is, there is a phase change at reflection. If c2 = c1 (i.e. if there is only one sort of rope) there is no reflection (because there is no boundary!). In the above analysis, we considered a simple sine wave. However, any function, even a nonperiodic funct ...

The fact that the topological invariant is a vector, and not a scalar, is an indication that they are essentially anisotropic. This anisotropy can be made more apparent because each WTI phase in d spatial dimensions can ...
