We propose a general capacitive model for an antidot, which has two localized edge states with different spins in the quantum Hall regime. The capacitive coupling of localized excess charges, which are generated around the antidot due to magnetic flux quantization, and their effective spin fluctuation can result in Coulomb blockade, h/(2e) Aharonov-Bohm oscillations, and the Kondo effect. The r...

A large area antenna generates a plasma by both inductive and capacitive coupling; it is an electromagnetically coupled plasma source. In this work, experiments on a large area planar RF antenna source are interpreted in terms of a multi-conductor transmission line coupled to the plasma. This electromagnetic treatment includes mutual inductive coupling using the complex image method, and capaci...

Cardiac muscle is a syncytial tissue of electrically coupled cells in which excitation of one cardiomyocyte spreads to all cardiomyocytes. Mechanisms of cell coupling in myocardial tissue can be categorized in two main groups: mechanisms that connect the intracellular parts of myocytes together (i.e., gap junctions), and mechanisms that act through changes in the small extracellular space of in...

Experiments are presented to describe the effect of capacitive coupling of two electrochemical oscillators during Ni dissolution in sulfuric acid solution. Equivalent circuit analysis shows that the coupling between the oscillators occurs through the difference between the differentials of the electrode potentials. The differential nature of the coupling introduces strong negative nonisochronic...

We introduce a versatile method to control the quality factor Q of a conducting cantilever in an atomic force microscope (AFM) via capacitive coupling to the local environment. Using this method, Q may be reversibly tuned to within 10% of any desired value over several orders of magnitude. A point-mass oscillator model describes the measured effect. Our simple Q control module increases the AFM...

A model is proposed to describe the local connection between the capacitive and the inductive unbalance functions of two neighbouring twisted pairs. A realistic simulation of the unbalance functions indicates that the constant ratio of the inductive unbalance with respect to the capacitive unbalance is a workable model. Using this model, it is demonstrated that the calculation of the reflective...

In order to realize bandpass filter with Chebyshev and elliptic function responses using a single resonator only, a dual-mode square resonant structure is proposed. Four small square loops are added into a large loop. One of small loops is defined a perturbation element, other small ones are references. By changing the thickness of the perturbation element with respect to that of a reference el...

Capacitive micromachined ultrasonic transducers ~CMUTs!, introduced about a decade ago, have been shown to be a good alternative to conventional piezoelectric transducers in various aspects, such as sensitivity, transduction efficiency, and bandwidth. In this paper, we discuss the principles of capacitive transducer operation that underlie these aspects. Many of the key features of capacitive u...

Plasma densities produced by half-and full-wavelength helical antennas in helicon discharges are compared. Contrary to theoretical expectations, half-wavelength antennas are more efficient than full-wavelength ones in producing plasma downstream. This effect is probably caused by capacitive coupling , which interferes with inductive coupling and is not included in the computations.

| Crosstalk noise in long interconnections is studied based on capacitive coupling and inductive coupling. It is shown that pulse noise is induced due to inductive coupling in heterogeneous insulators. The pulse noise becomes predominant noise factor on the condition that lines become longer, line resistance become lower, the signal raising time becomes faster and dielectric constant of materia...
