#### Modes in inhomogeneous slab waveguides

(1974)

In this correspondence we have developed the perturbation approach for the calculation of propagation constants for some of the practical slab waveguides and have shown the applicability of the approach to systems of ...

#### Nonlinear reflection and transmission of electromagnetic waves by moving plasmas

(1971)

Based on the covariance principle of Maxwell's equations and phase-invariance principle (derived from the special theory of relativity), expressions for the nonlinear reflection and transmission of electromagnetic waves ...

#### Modes in optical waveguides formed by silver-sodium ion exchange

(1978)

Exact solutions of the scalar wave equation for the guided modes of planar optical waveguides formed by silver-sodium ion exchange have been obtained. It has been shown that there is good agreement between the exact solution ...

#### Distortion of electromagnetic pulses undergoing total internal reflection from a moving dielectric half-space

(1973)

Using the covariance of Maxwell's equations and the phase invariance principle of plane waves, distortion of the electromagnetic pulses undergoing total internal reflection from a moving dielectric half-space has been ...

#### Propagation of waves in a medium varying transverse to the direction of propagation

(1974)

For an inhomogeneous dielectric in which the dielectric constant ε depends onxonly, it has been shown that it is possible to consider modes propagating in thezdirection havingH_{x} = 0orE_{x} = 0such that other field ...

#### Error Bounds and bandwidth in binary systems using nyquist pulses

(1971)

Intersymbol interference upper error bounds are calculated for the Gaussian-weighted sinc and raised-cosine families by using the Chernoff bound since this technique yields a value smaller than the worst case bound. A ...

#### On simplification of unstable systems using Routh approximation technique

(1978)

A modified modeling procedure using the direct Routh approximation method (DRAM) for a class of unstable systems has been presented in this technical note. The proposed method yields a model which is based on an improved ...

#### Least-squares state estimation in time-delay systems with colored observation noise: An innovations approach

(1975)

the method of innovations approach has been applied to develop an algorithm for the least-squares state estimation of a non-stationary linear discrete system with multiple time-delays, based on observations involving ...

#### A novel theorem with potential application to automatic equalization

(1979)

When the signs of the alternate terms of a symmetric discrete time series are reversed and the resultant series is convolved with the original, the newly created time series will have alternate values equal to zero. This ...

#### On the Lyapunov design of systems with zeros in the right-half plane

(1970)

The effect of a zero in the right-half plane on the controller derived through the stability theorem of Lyapunov is considered through a simple illustrative example. It is shown that the controller should have the form of ...
