Stimulated Brillouin scattering of obliquely propagating extraordinary electromagnetic waves off ion-Bernstein waves in plasmas 

Tripathi, Y K; Sharma, R P (1989)
The parametric decay of an obliquely propagating extraordinary electromagnetic wave into another extraordinary electromagnetic wave and a low-frequency electrostatic ion-Berstein wave via the stimulated Brillouin scattering ...

Study of thermal performance of a black liquid shallow solar pond under various operating conditions 

Verma, R; Prakash, J; Garg, H P (1989)
A black liquid solar collector cum storage system is studied. The liquid, being black, absorbs most of the radiation; also there is little reflection loss from the water surface. The performance of the system has been ...

Vector modes of an optical fiber in the weakly guiding approximation 

Thyagarajan, K; Ghatak, A K; Sharma, A (1989)
The authors show that starting from the appropriate linear combinations of LP modes, the weakly guiding approximation of the hybrid modes can be easily obtained without any reference to the rigorous vector modes. The ...

Explanation of polarisation dependence of differential phase shift in two-mode elliptic-core fibre strain gauges 

Pal, B P; Priye, V; Varshney, R K; A Kumar (1989)
An appropriate elliptic-core fibre theory is applied to model the differential phase shift between the first- and second-order modes observed in recent experiments on two-mode elliptic-core fibres subjected to longitudinal ...

Analysis of single mode inhomogeneous planar waveguides 

Mishra, P; Sharma, A (1986)
A new method for obtaining the propagation characteristics of single mode inhomogeneous planar waveguides is presented. The method is based on the scalar variational principle and a new trial field-the cosine-exponential ...

Analytical approximations for the propagation characteristics of dual-mode fibers 

Hosain, Shaikh Iqbal; Sharma, Enakshi Khular; Sharma, Anurag; Ghatak, Ajoy K (1983)
In this paper we present accurate analytical approximations for the modal fields of dual-mode optical fibers with power law profiles based on a scalar variational analysis. We propose single parameter and two parameter ...

Matrix method for determining propagation characteristics of optical waveguides 

Sharma, E; Ghatak, A; Goyal, I (1983)
We have transformed the scalar wave equation into a matrix eigenvalue equation, the diagonalization of which gives the guided modes and a discrete representation of the radiation modes. The method is simple and can be used ...

Propagation characteristics of single mode optical fibers with arbitrary index profiles: A simple numerical approach 

Sharma, Enakshi Khular; Sharma, Anurag; Goyal, I C (1982)
We present here a rapidly converging numerical procedure for the direct evaluation of the propagation constant and its first and second derivatives in single mode optical fibers with arbitrary refractive index profiles. ...

Calculation of cutoff frequencies in optical fibers for arbitrary profiles using the matrix method 

Sharma, Enakshi; Goyal, I C; Ghatak, Ajay K (1981)
We here propose a simple numerical procedure to calculate the cutoff frequencies in optical fibers with any arbitrary refractive index profile including discrete numerical data from profile measurement. The cutoff problem ...

Polarization characteristics of elliptic-core fibers with stress induced anisotropy 

Arun Kumar; Shenoy, M; Thyagarajan, K (1987)
We present a simple analytical method to study birefringence and polarization mode dispersion (PMD) of elliptic-core fibers with uniform or differential stress in the fiber cross section. The model takes account of both ...
