On the designing of effective calculation algorithm for shielded multiconductor transmission lines
For the purpouse of designing of effective and universal calculation algorithm of the shielded multiconductor transmission lines parameters existing now rigorous methods of boundary value problems solutions are considered. At low frequencies the most preferred is the method of discrete singularities. A calculation algorithm of electromagnetic fields and dispersion characteristics of shielded multiconductor transmission lines based on mode matching method and recalculation formulas is suggested.
Calculation algorithm for shielded microstrip-, slot-, and micro-coplanar strip lines with finite strip thickness
A common algorithm for the three types of transmission lines is based upon the modified Fourier method (re-expansion). To convert the summation equation system to algebraic form, the direct and inverse calculation formulas are used in contrast to the Galerkin method.
Monte Carlo simulations of magnetovolume instabilities in anti-Invar systems
We perform constant pressure Monte Carlo simulations of a spin-analogous model which describes coupled spatial and magnetic degrees of freedom on an fcc lattice. Our calculations qualitatively reproduce magnetovolume effects observed in some rare earth manganese compounds, especially in the anti-Invar material YMn2. These are a sudden collapse of the magnetic moment which is connected with a huge volume change, and a largely enhanced thermal expansion coefficient.
