BACKGROUND Immuno-compromised patients such as those undergoing cancer chemotherapy are susceptible to bacterial infections leading to biofilm matrix formation. This surrounding biofilm matrix acts as a diffusion barrier that binds up antibiotics and antibodies, promoting resistance to treatment. Developing non-invasive imaging methods that detect biofilm matrix in the clinic are needed. The us...

A state-space synthesis procedure is given for linear timevarying passive impedance matrices. The synthesis uses only passive components. I N THIS PAPER, we consider linear lumped finite networks composed of interconnections of time-variable and passive resistances, capacitances, inductances, gyrators, and transformers. The main problem considered is to pass from an input-output, or port, descr...

Relationships between impedance parameters and scaling factors are derived using absolute stability and passivity. For this, the teleoperation system is represented as a two-port model with a hybrid matrix. Design procedure of the impedance parameters for the absolute stability of the teleoperator under the time delay is proposed. The validity of the proposed control scheme is demonstrated by e...

Habib and Rupp [3] provided analytical results for mutual coupling between multiple dipole antennas with angular or spatial separation. However, the method of deriving mutual coupling from mutual impedance involved several inconsistencies on which depend the final results of multiple antenna system capacity presented in their paper. First, the expression of mutual impedance matrix (12) in [3] i...

With high integration density of today’s electronic system and reduced noise margins, maintaining high power integrity becomes more challenging for high performance design. Inserting decoupling capacitors is one important and effective solution to improve the power integrity. The existing decoupling capacitor optimization approaches meet constraints on input impedance. In this paper, we show th...

magnetotelluric (mt) method is an important passive surface geophysical method which uses the earth’s natural electromagnetic fields to investigate the electrical resistivity structure of the subsurface. the depth of investigation of mt is much higher than that of other electromagnetic (em) methods (vozoff, 1991). for a general conductivity distribution in the earth, the horizontal electric fie...

Absfrset. The notion of the Cauchy indexof a real rational scalar function is generalized todefinc the Cauchy index of a real rational symmetric matrix in terms of the behavior of the matrix at real singularities of its elements. Alternative characterizations are obtained which flow from iepresenrations of the real rational matrix using a Laurent series, a matrix fraction description. and a sta...

We propose a model to study the statistical properties of the impedance (Z) and scattering (S) matrices of open electromagnetic cavities with several transmission lines or waveguides connected to the cavity. The model is based on assumed properties of chaotic eigenfunctions for the closed system. Analysis of the model successfully reproduces features of the random matrix model believed to be un...
