A microstrip ultra-wideband (UWB) filter with unique shape, compactness, simplicity of operation and flexible notch characteristics is introduced. It is based on the fundamental and harmonic characteristics of a 50 Ohm transmission line that is grounded at both ends. The filter possesses design flexibility in the sense that it can operate as a stand-alone UWB component or include simple additio...

In a car, there are several operating fields with different requirements regarding the corresponding bus system. Each of the bus systems mentioned above is used to serve a certain communication requirement between the automotive electronic components. The designer selects the appropriate bus system depending on the required safety level, the data transmission rate and the costs. For example, th...

A method for the inversion of block tridiagonal matrices encountered in electronic structure calculations is developed, with the goal of efficiently determining the matrices involved in the Fisher–Lee relation for the calculation of electron transmission coefficients. The new method leads to faster transmission calculations compared to traditional methods, as well as freedom in choosing alterna...
