“…Ongoing research efforts aim to improve diode limiter performance by reducing the recovery time of the Schottky diode device used in the limiter [17], exploring diamond-based devices with favorable thermal characteristics [18], or analyzing degradation characteristics within the PIN diode device [19]. Alternatively, some studies focus on altering the shape of a microstrip-line-based filter [20], while others implement a limiter function in the form of an energyselective surface by integrating diode elements at the antenna end [21][22][23]. There's also research that implements an EMP protection limiter by creating a slot shape on a PCB board within a waveguide and placing a diode element in the center [24].…”

A new waveguide-based diode limiter is proposed to protect microwave-amplifying receivers from high-power electromagnetic pulses. The diode limiter was designed and fabricated to exhibit low insertion loss for normal signals while effectively blocking high-power transient signals. The proposed structure incorporates a diode element positioned between vertically connected cylinders inside the waveguide, with a square-integrated structure symmetrically placed on both the top and bottom. The diode element is inserted beneath a thin rod. Under low incident power, the diode remains inoperative, maintaining an electrically open state. In the presence of high incident power, the diode activates, transitioning into an electrically short state. The newly proposed structure enables the cylinder's vertical movement, providing the advantage of adjustability to shift the center operating frequency of the diode limiter. It incorporates a bandpass filter structure for normal signals and a band-stop filter characteristic for transient signals. Moreover, the symmetrical square-integrated structure is employed to concentrate the surface current at the diode element, enhancing the changing state of the diode limiter. This configuration demonstrates a low insertion loss of 0.38 dB for normal signals and a blocking coefficient of 8 dB for transient signals at the 5.68 GHz operating frequency.

“…Later on, researchers turned their attention to energy-selective surfaces (ESS) because of the nonlinear reaction of PIN diodes to input power. Over the past few decades, various energy-selective surfaces have been suggested, and relevant papers have been published. − However, most of these studies have primarily concentrated on high-power microwave protection in the L-band and S-band frequencies, limiting their protection bandwidth. Attempts have been made to design multilayer structures to expand the protection bandwidth, but these structures lack conformal properties. , Hence, the development of a flexible and ultrawideband energy-selective surface (ESS) for HPM protection remains a significant challenge.…”

We propose a flexible energy-selective surface (ESS) with an extremely wide protection band for effective high-power microwave (HPM) protection in the field of electromagnetic biological effects. The ESS incorporates nonlinear devices onto the frequency selective surface to shield against electromagnetic radiation. Simulation results indicate that the designed ESS achieves an insertion loss of less than 3 dB for low power signals within the frequency range of 3.5–4.5 GHz. Moreover, the ESS provides extensive protection against HPM within the frequency range 0.1–7.5 GHz. We conduct a comprehensive full-wave simulation and successfully construct a prototype that performs exceptionally well, validating the consistency between the simulation and the experimental results.
