Abstract :
Until now, structures that exhibited negative-refractive-index properties were 3D in form and employed resonant elements. It is widely believed that such resonant elements are essential. The present paper introduces two new features: non-resonant elements in the periodic array, and the adaptation of these ideas to planar structures, such as strip line or microstrip line.
