Based on the active coupled line concept, a novel approach for efficient noise performance modeling of millimeter-wave field-effect transistors is proposed. This distributed model considers the effect of wave propagation along the device electrodes, which can significantly affect the noise performance especially in the millimeter-wave range. By solving the multi-conductor transmission line equa...

Sub-resonances often happen in wireless power transmission (WPT) systems using coupled magnetic resonances (CMR) due to environmental changes, coil movements or component degradations, which is a serious challenge for high efficiency power transmission. Thus self-tuning is very significant to keep WPT systems following strongly magnetic resonant conditions in practice. Traditional coupled-mode ...

in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

The development of a microfluidically cryo-cooled and inductively coupled spiral microcoil for magnetic resonance (MR) microscopy with high signal-to-noise ratio (SNR) is presented. The microcoil was inductively coupled to a secondary coil that was directly coupled to a transmission line. This configuration eliminated thermal flux through direct connection when the microcoil was cryo-cooled to ...

| Interconnect in VLSI circuits is best modeled as a lossy transmission line in high speed integrated circuits. Analytical expressions for the coupling noise between adjacent interconnect are presented to estimate the peak noise voltage on a quiet line based on the assumption that these interconnections are loosely coupled, where the e ect of the coupling noise on the waveform of an active line...

Frequency-dependent causal RLGC(f ) models are proposed for single-ended and coupled transmission lines. Dielectric loss, dielectric dispersion, and skin-effect loss are taken into account. The dielectric substrate is described by the two-term Debye frequency dependence, and the transmission line conductors are of finite conductivity. In this paper, three frequency-dependent RLGC models are stu...

Periodically nonuniform coupled microstrip line (PNCML) loaded with transverse slits is characterized using the fullwave method of moments and short-open calibration technique. Guided-wave characteristics of both evenand odd-modes are thoroughly investigated in terms of two extracted per-unit-length transmission parameters, i.e., phase constants and characteristic impedances. As such, frequency...
