光学Tamm态是一种界面模，也称为Tamm等离子体激元。在基于微带传输线的光子异质结构中实验观察到了它们。在有效阻抗匹配和有效相移匹配的条件下，可以精确地设计光学Tamm态的位置。研究结果表明，光子带隙可以作为负介电常数或负磁导率介质来构造界面模。模拟结果与实验结果吻合较好。
Optical Tamm states, a kind of interface modes, are also called Tamm plasmon-polaritons. They are experimentally observed in photonic heterostructures based on microstrip transmission lines. The position of optical Tamm states can be designed exactly under effective impedance match and effective phase shift match conditions. Our results show that the photonic band gaps can have the effect of negative-permittivity or negative-permeability media in constructing the interface modes. The simulations and experimental results agree with each other quite well.
