In this paper, a miniaturized, low-profile, self-actuated radome is designed for achieving field intensity dependent electromagnetic (EM) protection in a working frequency band. The radome is periodic with each unit loaded with four microwave diodes. The demension of the unit is in size of λ/12 and is ultrathin. A full-wave simulation is carried out for obtaining the transmission characteristic of...
In this paper, a miniaturized self-actuated bandpass protection structure with filtering and limiting functions is presented. Based on energy low-pass mechanism, this protection structure is sensitive to the power density or field intensity of incident wave. The unit cell dimensions and periodicities are sub-wavelength which is in the order of λ/15. Mechanism of operation, structural design, and full-wave...
