## Abstract

To calculate the losses in a thin open metal screen caused by its nonideal conductivity, it was proposed that the actual screen be replaced by an 'effective,' infinitely thin surface having an impedance of special form. The impedance Z was formulated so that the real part of Z correctly described the dissipative properties of the metal and the imaginary part provided the correct induced current density at the edge. This quantity is determined only by the shape of the edge; IM Z contains the parameter ρ with the dimension of length, characterizing the edge geometry. Geometric models of a real screen of interest are of two types: a half-plane of finite thickness with curved and sharp edges.
