ANALYSIS OF OPTICAL WAVEGUIDES USING AN ANALOGY TO A MECHANICAL VIBRATION PROBLEM

E. BAUM

Many waveguide problems in integrated optics may mathematically be described by a scalar Helmholtz equation. In this paper it will be shown, that the same equation arises in the…

MATHEMATICAL AND NUMERICAL ANALYSIS OF THE SPREADING RESISTANCE OF SEMICONDUCTOR BURIED RIDGE STRIPE LASERS

K. SOUISSI, A. PARASKEVOPOULOS, P. DEVOLDÈRE, E. CAQUOT

A 2D numerical simulation using a finite element technique is presented for computing spreading resistance of a semiconductor buried ridge stripe laser. The simplified physical…

ROTATIONAL‐TRANSLATIONAL ADDITION THEOREMS FOR VECTOR SPHEROIDAL WAVE FUNCTIONS

M.F.R. COORAY, I.R. CIRIC

Rotational‐translational addition theorems for the vector spheroidal wave functions Ma(i)mn(h; ξ, η, φ) and Na(i)mn(h; ξ, η, φ), i = 1,2,3,4, are derived from those for the…

A SENSITIVITY ANALYSIS OF THE STEADY STATE SEMICONDUCTOR DEVICE EQUATIONS

Herbert STEINRÜCK

When considering the one dimensional semiconductor device equations, the condition number turns out to be so large that a numeric solution of the equation is meaningless. Applying…

REMARKS ON THE ASCENT ALGORITHM FOR THE LINEAR MINIMAX PROBLEM

Henryk UGOWSKI

In this note we correct the flow diagram of the ascent algorithm for the linear minimax problem which was shown by Cheney on p. 50.
