本文介绍了一种新的传输线能量积累原理，这种传输线具有随空间和时间变化的LC参数--一种源于动态材料概念的效应。我们认为，棋盘形材料组件创建的一个周期性的时间“翻转”的属性的空间层压板从两种不同的物质。在材料和结构参数的一些扩展范围中，由于在时间属性切换的时刻外部源所做的功，在行进通过该组件的波中保持能量的指数增长。的效果是数值模拟的等效LC电路。
This letter introduces a new principle of energy accumulation in transmission lines with the LC parameters varying in space and time-an effect emerging from the concept of dynamic materials. We consider a checkerboard material assembly created by a periodic temporal “flip over” of the properties of spatial laminates fabricated from two different substances. In some extended ranges of material and structural parameters, an exponential growth of energy is maintained in waves traveling through this assembly due to the work done by an external source at the moments of temporal property switching. The effect is numerically demonstrated for an equivalent LC circuit.
