## Abstract In this article we study congruences of lines in ℙ^__n__^, and in particular of order one. After giving general results, we obtain a complete classification in the case of ℙ^4^ in which the fundamental surface __F__ is in fact a variety, i.e. it is integral, and the congruence is the ir
The dispersion characteristics of the effecti¨e dielectric constant and the characteristic impedance of a superstrate-loaded cylindrical microstrip line are examined. Numerical results of fundamental and higher order modes are computed using a spectral-domain integral equation formulation in conjunc
