In this paper, the propagation of electromagnetic waves through an infinite slab of uni- or bi- axial chiral medium is analytically formulated for an arbitrary incidence using 4×4 matrix method. In this powerful method, a state vector differential equation is extracted whose solution is given in terms of a transition matrix relating the tangential components of electric and magnetic fields at t...

A principle and design procedure of differential phase shifters and baluns with a specified bandwidth is given. Phase shifters and baluns proposed here comprise of two transmission lines(TL), one is conventional while the other is CRLH-TL. The operating frequency is properly chosen as to obtain a maximum bandwidth. The bandwidth is related to number of unit cells comprising CRLH-TL.A Wilkinson ...

This paper pertains to speech and acoustic signal processing, particularly to the determination of echo path delay and operation of echo cancellers. To cancel long echoes, the number of weights in a conventional adaptive filter must be large. The length of the adaptive filter will directly affect both the degree of accuracy and the convergence speed of the adaptation process. We present a new a...

In this thesis, we revisit differential and non–coherent transmission techniques over fading channels. In particular, we consider receiver design for differential space–time modulation (DSTM) over correlated multiple–input multiple– output (MIMO) fading channels and the performance analysis of differential phase shift keying (DPSK) and non–coherent frequency shift keying (FSK) in generalized K–...

Electron transport properties of pure and Oxygen and/or Methyl substituted pyrene between two semi-infinite Aluminum atomic electrodes have been investigated by means of density functional theory plus the non-equilibrium green’s function method. The electrodes were represented by a slab of Al atoms oriented along the [111] plane. The computations were carried out in the bias voltage range of 0....

In restructured power market, power producers and customers utilize the transmission network and try to maximize their benefits. Hence it is important to improve the static ATC for allowing more transaction in future without any transmission limit violation. This paper suggests the method for establishing bilateral/multilateral transaction based on the optimal generator selection and it’s shari...

Wireless communication technology has seen a remarkably fast evolution due to its capability to provide a quality, reliable and high-speed data transmission amongst the users. However, transmission of information in wireless channels is primarily impaired by deleterious multipath fading, which affects the quality and reliability of the system. In order to overcome the detrimental effects of fad...
