英文摘要： Transmission stealth technology is a newly-emerging stealth techonology, which is of great application values in military domain. Dealing with the design and realization of low-band transmission stealth, this project proposes a new way of realizing transmission stealth by using the high-efficiency couplings between unit cells of meta-surfaces. With this aim in mind, we will carry out in-depth investigations into the electromagnetic transmission principles, illustrate the coupling and hybridization effects between metasurface unit cells, analyze the physical mechanism and technical route of meta-surface design. Physical analysis model will be established to obtain the influecnes of unit cell geometrical parameters, material parameters, substrate loss, coupling layer thickness, etc. By combining the electromagnetic theory and dielectric theory and considering the inter-cell coulings, physical mechanism of transmission stealth will be investigated profoundly and comprehensively. Finally, the physical mechanism and design method of realizing transmission stealth by meta-surfaces will be investigated. Test samples will be fabricated to verify the meta-surface transmission stealth. This project will open an new route to low-band transmission stealth. The investigation results will be promising in solving the thickness
