In recent years, metasurfaces composed of lumped nonlinear circuits have been reported to exhibit the capability detecting specific electromagnetic waves, even when waves are same frequency, depending on their respective waveforms or, more precisely, pulse widths. Herein, three types metasurface absorbers (MSAs) presented which a square‐patch structure loaded with linear circuit components, including resistors or in parallel capacitors/inductors, can mimic waveform‐selective absorption behavior terahertz (THz) region. By judiciously selecting suitable values for these MSAs achieve near‐perfect incident continuous longer pulses while exhibiting reduced short at THz frequency. These structures be referred as pseudo‐waveform‐selective because characteristics primarily derived from dispersion resonator structures, opposed frequency conversion commonly observed circuits. outcomes and discoveries introduce an additional degree freedom waveform discrimination range, potentially enabling broader range applications, but not limited detection, sensing, wireless communication.

Ultra-broadband and efficient terahertz (THz) absorption is of paramount importance for the development high-performance detectors. These detectors find applications in next-generation wireless communications, military radar systems, security detection, medical imaging, various other domains. In this study, we present an ultra-wideband THz wave metasurface absorber (UTWMA) featuring a composite surface microstructure multilayer absorbing material (graphene). This UTWMA demonstrates remarkable capabilities by achieving highly levels, reaching 96.33%, within 0.5-10 frequency range. To enhance efficiency precision design process, have incorporated artificial neural networks, which enable rapid accurate parameter selection. Moreover, conducted comprehensive analysis mechanism exhibited at different frequencies. combines insights from electric field distribution effective medium theory. The findings presented paper are expected to catalyze further research domain broadband technology, particularly context metasurfaces related fields. Additionally, work paves way compact, supercontinuous photovoltaic or photothermal electrical devices.
