On-chip transmission line modelling and design become increasingly important as frequencies are continuously going up. This paper explores possibilities to implement transmission lines on CMOS ICs via coupled coplanar strips. EM-field simulations with SONNET are used to estimate important transmission line properties like characteristic impedance, propagation velocity and loss in a 0.18 micron ...

With the development of distributed renewable generations, a large number generations (DGs) are connected to microgrid. Therefore, cooperative algorithms more suitable for optimal dispatch microgrid than centralized algorithms. This paper proposes novel control method microgrids, considering line losses and time delay. First, optimization model is established, optimality conditions obtained. Se...

This paper deals with the problem of estimating the losses in highly-conducting wires, in a frequency range where the transverse dimension is comparable to the signal wavelength. In this case the standard transmission line model fails since it cannot predict high-frequency effects like radiation in the transverse plane. Here we use a recently proposed enhanced transmission line model which, alt...

The paper presents a new method for on-line temperature calculation taking into account change in the tap changer position. The method introduces accurate calculation of the losses, depending on the current, average temperature of the winding, and tap changer position (it affects both Joules (DC) losses and stray losses). The thermal model itself is the common three-body model (for a transforme...

Several mechanisms may heat the solar chromosphere: acoustic waves, magnetoacoustic waves (slow, fast, and Alfvén waves), and small-scale magnetic reconnections. Based on observations in the Ca II 854.2 nm line, the contribution of acoustic waves to the heating of quiet and plage regions in the chromosphere is discussed. The energy released by radiative losses is compared with the energy deposi...

We study disorder-induced propagation losses of guided modes in photonic crystal slabs with line-defects. These losses are treated within a theoretical model of size disorder for the etched holes in the otherwise periodic photonic lattice. Comparisons are provided with state-of-the-art experimental data, both in membrane and Silicon-on-Insulator (SOI) structures, in which propagation losses are...
