Abstract
Two-dimensional communication (2DC) is a wireless communication system using a waveguide sheet as a radio frequency (RF) signal transmission medium. This paper proposes a theoretical analysis model of RF radiation from a 2DC sheet surface. Previous works supposed that only a non-radiative guided mode propagates along a 2DC sheet and that radiation is due only to open ends of the sheet or to impedance discontinuities around the sheet edges. The proposed model based on field equivalence principle clarifies that the sheet guided mode propagating in a finite-size sheet inherently generates radiation fields even if no edge radiation nor impedance discontinuity are involved.
