Metamaterial has become a hotspot in many research fields, including electromagnetism, thermodynamics and mechanics, as it can offers additional design freedom for material to obtain novel properties. Especially for the electromagnetic devices, various interesting electromagnetic properties which cannot be found in nature materials can be realized, such as negative refraction, invisible cloak, etc. Herein, we provide an overview of paper-based metamaterial for microwave application. This work reviews the metamaterial realized on paper substrate, including the fabrication techniques, application fields, as well as the outlook on future directions of the paper-based metamaterial for the readership.

“…In the late 2000s, new MMA fabrication methods were introduced, such as ink-jet printing [4] and additive manufacturing [2]. Among the MMA printing techniques, conductive carbonbased printing has provided the best overall performance for MMAs [5]. Therefore, the majority of previous investigations over the past decade have been focused on inkjet printing technology for depositing carbon-based conductive inks owing to its high resolution at the microscale level and the high uniformity of the deposited layer thickness [6].…”

Microwave absorbion for radar stealth technology is facing challenges for effectiveness in the low frequency region. Here we report a new laser-based method to produce an ultra-wideband metamaterial based microwave absorber with a high sheet resistance uniformity and negative magnetic permeability leading to the highest relative bandwidth and lowest thickness in the L to S band reported so far. Control of electrical sheet resistance uniformity has been achieved to less than 5% deviation for 400 Ω/sq and 6% deviation for 120 Ω/sq, leading to a microwave absorption coefficient between 97.2%-97.7% within 1.56 GHz-18.3GHz bandwidth for incident angles of 0-40, and there is no need for applying energy or an electrical power source during operation. Porous N- and S- doped turbostratic graphene 2D patterns with imbedded magnetic nanoparticles are produced on polyethylene terephthalate simultaneously during laser direct writing. The proposed low frequency, wide band, wide incident angle and high electromagnetic absorption microwave absorber would have the potential for aviation, EMI suppression and 5G applications.

“…One of them is to be a reinforcement providing all the mechanical properties of the composite. The reinforcement textile is then coated 20 or printed 21 by MLAs or/and DLAs function particles that are diffused in the transparent resin 22,23 in the formation process. In this role, the textile can not attenuate any EMW energy.…”

The range and strength of Electromagnetic Wave loss are increasing with the development of electronic technology in intellectualization and diversification. Extensive research is focused on high-frequency microwave absorbersbut rarely on low-frequency ones. However, the shield of low-frequency microwave interference is bulky and complicated. It is necessary to adopt new structural composites with lightweight, porous, or multi-layer magneto-dielectric synergistic to obtain lighter, thinner, broader bandwidth, and strong absorption absorbers in the low-frequency range. The porous and multi-layer textiles would extend the Microwave (M. W.) transmitting pathway. The prepared M. W. textile-based composites possess broad bandwidth and strong absorption in the low-frequency range when magneto-dielectric synergistic functional particles have embedded in the textiles. This paper reviewed the modified graphene-based absorbers (GBAs), the hybrids combined GBAs with the low-frequency magnetic loss absorbers (LFMLAs), and the textile-based composites added by the complex combined GBAs with LFMLAs (GBAs/LFMLAs). The prepared GBAs/LFMLAs textile-based composites are broad bandwidth, lightweight, small thickness, and strong absorption materials in the low-frequency range. The prepared GBAs/LFMLAs textile-based microwave absorbers (MWAs) may expand the application scope of MWAs and promote their economic benefit. The GBAs/LFMLAs textile-based composites may propose a new strategy of broad bandwidth MWAs in the low-frequency range.
