Zusammenfassung: Multidimensional lossless networks are of interest, for example, for use as reference filters for multidimensional wave digital filters. Necessary properties of the scattering matrix of such multiports have been established. In the design of k-dimensional reactance networks it is of great interest whether these mentioned features are also sufficient for a given matrix to be the scattering matrix of such a system, or not. It is shown that this is not the case for dimensions greater than two. Hence, no general synthesis procedure for multidimensional reactance multiports exists, as is in the one- and two-dimensional cases

Schlüsselwörter: all-pass filters, all-pass functions, linear network synthesis, lumped elements, lumped parameter networks, multidimensional wave digital filters, partial degree, partial denominator polynomial, polynomials, rational reflectance, two-variable polynomial, wave digital filters3-D lossless first-order one ports

Zusammenfassung: A special class of 3-D lossless one ports is considered. The author restricts his investigation to all-pass functions where the partial degree, with respect to every complex variable pi, i=1 to 3, of its partial denominator polynomial does not exceed 1. The synthesis is achieved by reducing the given problem to the known synthesis of 2-D lossless multiports by the extraction of p1-type reactive elements. The author makes use of the fact that a real, nonnegative, definite, two-variable polynomial can be written as a sum of squares of real polynomials if its total degree does not exceed four. No restrictions are made concerning the coefficients of the rational reflectance of the desired network: they can be either real or complex, so as to include even complex networks which are of special interest for multidimensional wave digital filters
