“…The third type is resonant and non-resonant FSSs, consisting of one or several metal layers embedded with dielectric substrates to form special filters [21][22][23][24][25][26][27][28][29]. Also, in addition to the above three FSSs, 2D metamaterials have also attracted more attention in recent years, opening up new horizons in electromagnetic wave modulation [30][31][32][33][34].…”

We design a frequency selective surface (FSS) capable of transmitting K-band and reflecting Q-band radio waves. The equivalent circuit approach assists the distribution of multi-layer FSS to achieve a third-order bandpass response with an incident angle of less than 30°. The unit structure consists of three metal layers embedded with two dielectric substrates. Especially, the FSS provides a 3 dB transmission bandwidth range from 18.6 to 26.7 GHz with a maximum measured insertion loss of 0.61 dB. Hence the proposed polarization-sensitive FSS with low insertion loss can be applied in the observation system of millimeter astronomy.

“…[20,21] Recently, 2D transition metal carbides and/or nitrides Ti 3 C 2 T x have attracted attention in the field of electromagnetic shielding due to their unique layered structure, abundant functional groups, and excellent electrical conductivity. [22][23][24] A Ti 3 C 2 T x film could still hold an electrical conductivity of 15100 S cm −1 in a thickness of 214 nm. [25] Usually, the good electro-thermal conversion performance relies on excellent electrical conductivity.…”

Highly robust flexible multifunctional film with excellent electromagnetic interference shielding and electrothermal/photothermal characteristics are highly desirable for aerospace, military, and wearable devices. Herein, an asymmetric gradient multilayer structured bacterial cellulose@Fe3O4/carbon nanotube/Ti3C2Tx (BC@Fe3O4/CNT/Ti3C2Tx) multifunctional composite film is fabricated with simultaneously demonstrating fast Joule response, excellent EMI shielding effectiveness (EMI SE) and photothermal conversion properties. The asymmetric gradient 6‐layer composite film with 40% of Ti3C2Tx possesses excellent mechanical performance with exceptional tensile strength (76.1 MPa), large strain (14.7%), and good flexibility. This is attributed to the asymmetric gradient multilayer structure designed based on the hydrogen bonding self‐assembly strategy between Ti3C2Tx and BC. It achieved an EMI SE of up to 71.3 dB, which is attributed to the gradient “absorption–reflection–reabsorption” mechanism. Furthermore, this composite film also exhibits excellent low‐voltage‐driven Joule heating (up to 80.3 °C at 2.5 V within 15 s) and fast‐response photothermal performance (up to 101.5 °C at 1.0 W cm−2 within 10 s), which is attributed to the synergistic effect of heterostructure. This work demonstrates the fabrication of multifunctional bacterial cellulose@Fe3O4/carbon nanotube/Ti3C2Tx composite film has promising potentials for next‐generation wearable electronic devices in energy conversion, aerospace, and artificial intelligence.
