This paper presents a new approach to solve two-dimensional transverse magnetic (TM) scattering problems involving homogeneous penetrable scatterers. The scatterers can be replaced by equivalent electric surface currents provided a proper surface admittance operator is introduced relating those currents to the electric fields on the scatterer’s surface. The surface operator for a scatterer with...

OBJECTIVES To determine the long-term change in static admittance values of subjects with a positive or negative history of otitis media (OM) and ventilation tube (VT) insertion; and to investigate the association between static admittance values and tympanic membrane abnormalities. DESIGN Prospective follow-up study. SUBJECTS A total of 358 subjects with or without a history of OM (OM+ or ...

This article considers the problem of estimating parameters compound admittance matrix three-phase untransposed low- and medium-voltage electrical distribution networks using synchrophasor measurements from phasor measurement units (PMUs). The work proposes analyzes performance a preprocessing strategy on PMU's raw measurements, which consists in grouping clusters and, then, averaged each clust...

Pseudo-admittance is introduced as a novel bilateral telemanipulation system that is designed to mimic proportional-velocity admittance control on systems where the master is an impedance-type robot. The controller generalizes to systems with slave robots of the impedance or admittance type. Pseudo-admittance uses a proxy with admittance dynamics combined with direct force feedback from the sla...

A sensor for measuring adsorption on a substrate has been designed including a contactless detection scheme, called supercapacitive admittance tomoscopy (SCAT). The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side and a chemically modified surface on the other onto which the adsorption of molecules occurs. Upon application of a high frequency ac voltage...

A new formulation of the Chandezon method for crossed gratings is presented. In the nonorthogonal translation coordinate system, an arbitrary field in a homogeneous source-free region can be expressed as the sum of a TE field and a TM field. It is shown that the whole solution can be derived from the eigensolutions of an operator independent of the polarization. In addition, use is made of the ...

In this paper, we have analyzed the Double-Pole Four-Throw Double-Gate Radio-Frequency Complementary Metal-Oxide-Semiconductor (DP4T DG RF CMOS) switch using S-parameters for 1 GHz to 60 GHz of frequency range. DP4T DG RF CMOS switch for operation at high frequency is also analyzed with its capacitive model. The results for the development of this proposed switch include the basics of the circu...

The shape of enveloped viruses depends critically on an internal protein matrix, yet it remains unclear how the matrix proteins control the geometry of the envelope membrane. We found that matrix proteins purified from Newcastle disease virus adsorb on a phospholipid bilayer and condense into fluidlike domains that cause membrane deformation and budding of spherical vesicles, as seen by fluores...

The increasing use of power electronics converters to integrate renewable energy sources has been subject concern due the resonance oscillatory phenomena caused by their interaction with poorly damped AC networks. Early studies are focused assess controller influence a single converter connected simple networks, and they no longer representative for existing systems. Lately, multi-infeed grid-c...
