The modal transmission-line (MTL) method is used to analyze the shielding effectiveness of buildings, which is an important parameter for the accurate planning of microcellular communication networks. For that, the buildings are modeled as multilayer lossy periodic structures. After a description of the extended MTL-theory, the newly developed MTL model is applied to brick walls, reinforced-con...

This paper presents the modeling and simulation of simultaneous switching noise (SSN) in on-chip power distribution networks (PDN). The circuit model of power buses over lossy silicon substrate is extracted as frequency dependent RLGC elements. The coupling between conductors on adjacent layers is represented as coupling capacitors. Accurate analytical formulae are derived to extract the RLGC t...

In this paper, new formulations for the energy dissipation of lossy transmission lines driven by CMOS inverters are provided, and a new performance metric for the energy optimization under the delay constraint is proposed. The energy formulations are obtained by using approximated expressions for the driving-point impedance of lossy coupled transmission lines which itself is derived by solving ...

Time-domain transmission line analysis has been a subject of interest in recent microwave studies and in interconnect analysis and simulation. For the analysis of linear microwave circuits, we use frequency-domain scattering parameters to evaluate circuit performance. The time-domain responses of such a circuit are obtained by taking the inverse Laplace transforms of corresponding frequency dom...

in this paper, an object-based, highly scalable, lossy-to-lossless 3d wavelet coding approach for volumetric medical image data (e.g. mr and ct) is proposed. the new method, called 3dobhs-spiht, is based on the well known set partitioning in hierarchical trees (spiht) algorithm and supports both quality and resolution scalability. the 3d input data is grouped into groups of slices (gos) and eac...

A method for design and implementation of a compact via-less Composite Right/Left-Handed Transmission Line (CRLH TL) is presented. By introducing a new circuit model, the CRLH transmission line behavior is studied versus the parameters variations to achieve the desired characteristic impedance and electrical length. Then a compact quarter wavelength CRLH transmission line with 70 Ω characte...

This dissertation focuses on packet-level systematic network coding (SNC) schemes to provide resilience to packet losses in lossy line networks. In theory, network coding is known to improve throughput and reliability of lossy networks. However, the translation of the network coding theory into efficient practical network coding solutions involves some critical challenges. This dissertation add...

A novel electromagnetic transient analysis technique by means of the orthogonal projection method for lossy transmission line is proposed. By employing the proposed method, the traveling waves propagating from one terminal to another can be quickly obtained with less amount of computation at considerably large steps. First of all, the differential function to variable time can be approximated t...
