Analysis of transmission line equations at high frequency*
1999 International Conference on Computational Electromagnetics and its Applications. Proceedings (ICCEA'99) (IEEE Cat. No.99EX374), 2003The limitations of the classical transmission line equations may cause a large error when using them to deal with EM problems at very high frequency. On the basis of the Maxwell equations, with the help of the integration equation method, new transmission line equations are induced in the frequency domain, and the results of a special situation from ...

A gyrotron frequency detuning equation
International Journal of Infrared and Millimeter Waves, 1983Estimates of gyrotron frequency detuning obtained from a small-signal analysis are compared with numerical calculations. There are significant differences under normal operating conditions.

On the frequency dependent Lyapunov equation
IEEE Transactions on Circuits and Systems, 1986A frequency dependent Lyapunov equation was recently used in the stability analysis of two-dimensional (2-D) digital systems, but no general solution was developed. In this paper a general form of the frequency dependent Lyapunov matrix is proposed and a set of equations which completely characterize the solution are derived.

Tomography in frequency domain using wave equation
International Journal of Modelling, Identification and Control, 2010Computed tomography technology has been widely applied in many fields such as geographical structure detection, industrial detection and clinical diagnosis. In some situations the image quality is not high due to the measurement errors and disturbances.

Matrix Equations for the Determination of Beam Natural Frequencies
Journal of the Society for Industrial and Applied Mathematics, 19601. Introduction. A general matrix equation is developed by which it is possible to determine the frequencies and modes of a beam vibrating in coupled beam bending, beam shear and torsion, with the effects of mass, torsional moment of inertia and rotary moment of inertia included.
