提出了一种可编程混合电路，该电路由两个加载变容二极管的可重构欺骗表面等离子体激元（SPP）波导和一个基片集成波导（SIW）组成。通过控制它们的色散行为，在混合电路中实现了带通效应，其中上、下截止频率分别由SPP波导和SIW决定。当两个SPP波导被配置为具有相同的截止频率高于基片集成波导的截止频率时，所提出的电路可以实现功率分配;当一个SPP波导被重新配置为拒绝来自基片集成波导的波时，该电路将是带通滤波器。作为一个典型的应用，一个逻辑“或”门与2位编码的设计通过编程的偏置电压施加到加载在SPP波导的单元结构的变容二极管。测量结果与数值模拟结果吻合较好。该工作在多功能集成电路和数字通信系统中具有更大的应用潜力。
A programmable hybrid circuit is proposed, which is composed of two reconfigurable spoof surface plasmon polariton (SPP) waveguides loaded with varactor diodes and a substrate integrated waveguide (SIW). By manipulating their dispersion behaviors, the band-pass effect is achieved in the hybrid circuit, in which the upper and lower cutoff frequencies are determined by the SPP waveguide and SIW, respectively. When two SPP waveguides are configured to have the same cutoff frequency that is higher than the SIW's cutoff, the proposed circuit can realize a power division; when one SPP waveguide is reconfigured to reject the waves from SIW, this circuit will be a band-pass filter. As a typical application, a logic "OR" gate with 2-bit coding is designed by programming the bias voltages applied to the varactor diodes loaded on the unit structures of the SPP waveguides. All functions are demonstrated by measurement results that agree with numerical simulations very well. The work provides more potential applications in multifunctional integrated circuits and digital communication systems.
