Table of contents
INTEGRAL SURFACES FOR HYPERBOLIC ORDINARY DIFFERENTIAL EQUATIONS WITH IMPULSES
S.G. HRISTOVA, D.D. BAINOVThe paper considers integral surfaces of systems of differential equations with impulse perturbations at fixed moments of time. Sufficient conditions have been obtained for the…
THE USE OF THE SINGULAR VALUE DECOMPOSITION METHOD IN THE SYNTHESIS OF THE NEUMANN'S BOUNDARY PROBLEM
JAN SIKORA, JERZY SKOCZYLAS, JAN SROKA, STANISLAW WINCENCIAKThis paper discusses an electrostatic, homogeneous field in a uniform two‐dimensional domain with Neumann's boundary conditions. The boundary conditions are known only at some…
THE INFINITE BOUNDARY ELEMENT AND ITS APPLICATION TO THE UNBOUNDED HELMHOLTZ PROBLEM
Y. KAGAWA, T. YAMABUCHI, Y. ARAKIThe combination method, combined finite element‐boundary element approach, is suitable for unbounded field problems. Although this technique attains a high degree of accuracy, the…
CUT‐OFF FREQUENCIES OF QUAD‐RIDGED WAVEGUIDES USED IN THE DESIGN OF MICROWAVE CIRCULAR‐POLARISERS
P. DALYIn microwave radio‐frequency technology, the design of broadband circular polarisers involves the use of waveguides having different propagation velocities for two orthogonal…
