This article presents a novel single-polarized, 1-bit reconfigurable holographic metasurface (RHM) capable of independent manipulating radiating and scattering patterns. The proposed architecture integrates a single PIN diode per unit cell to dynamically switch between distinct surface impedance states and reflection phases. This enables three concurrent functionalities: beam steering for radiating and scattering patterns; radar-cross-section (RCS) reduction through absorption; and polarization conversion, including linear-to-left/right hand circular polarization (LHCP/ RHCP) and cross-polarization transformations. A 32×24 reconfigurable metasurface array fed by a Rotman lens is designed, fabricated and measured. Experimental results show that the RHM can achieve E-plane beam steering from −30° to 60° and H-plane beam steering from −30° to 30° through surface impedance modulation and feeding port selection respectively, under 9 GHz surface wave (SW) excitation. Beam steering up to ±60° in E-plane is achieved across 11-15 GHz via programmed reflection phase gradients under space propagating wave (SPW) illumination.
