Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
(2004)
Among the wave propagation problems, those connected with half-spaces bounded by sectionally homogeneous boundaries take important place because they are motivated by microwave applications. If the boundary are of three ...
The general equation of motion via the special theory of relativity and quantum mechanics
(2004)
Herein we present a whole new approach to the derivation of the Newton's Equation of Motion. This, with the implementation of a metric imposed by quantum mechanics, leads to the findings brought up within the frame of the ...
An essential approach to the architecture of diatomic molecules. 1. Basic theory
(2004)
We consider the quantum mechanical description of a diatomic molecule of "electronic mass" m0e, "internuclear distance" R0, and "total electronic energy" E0e. We apply to it the Born-Oppenheimer approximation, together ...
A parametric approach to construct two-variable positive real impedance functions for the real frequency design of mixed lumped-distributed matching networks
(IEEE, 2004)
In this paper, a parametric approach to construct two-variable positive real driving point impedance functions characterizing lossless ladder networks with mixed lumped and distributed elements is presented. The proposed ...
Üç boyutlu akustik görüntüleme için ön alıcı-verici tümdevre
(IEEE, 2004)
Tıbbi ultrasonik görüntüleme sistemleri, genel olarak bir çevirici elemanı ve akustik işaretin üretilip algılanmasından sorumlu elektronik oluşmaktadır. Tek boyutlu dönüştürücü dizileriyle, incelenmekte olan ortamın iki ...
Pilot-aided bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
(IEEE, 2004)
This paper proposes a computationally efficient, pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ...
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
(IEEE, 2004)
This paper describes the development of an ultrasonic imaging system based on a two-dimensional capacitive micromachined ultrasonic transducer (CMUT) array. The transducer array and front-end electronics are designed to ...
