N2 - A kind of transmission-reflection-integrated elements and metasurfaces (MSs) are proposed to achieve full-space manipulation of amplitudes, phases, and polarization states of electromagnetic (EM) waves. The elements of MSs are designed to control the reflection and transmission under the same incident wave. By introducing an amplitude-phase regulation structure to each element, the amplitudes, phases, and polarization states of reflection and transmission can be simultaneously controlled by three geometric parameters of the proposed elements, respectively. To demonstrate the abilities of elements to regulate EM waves, the MSs working in the reflection mode, transmission mode, and transmission-reflection-integrated mode are designed and simulated, and their simulation results verify the designs. The transmission-reflection-integrated MS is also fabricated and experimentally measured. Its simulation and measurement results show that deflective vortex beams with different values of topological charge can be generated simultaneously and independently in both the reflection and transmission modes.
