[45] demonstrated an electrically tunable multi-band THz metamaterial filter based on graphene-integrated multiple-square-loop structures and realized the switch from a single-band to multi-band filtering by sweeping external voltages. Further, the THz filter can also be dynamically modulated by ...
band-edge transitionsrigid substrateWe make a flexible wideband bandpass filter at terahertz (THz) frequencies using multi-layer metamaterials. A very flat response in the passband can be obtained since the Fabry-Perot reflection inside the rigid substrate is eliminated. The center frequency is about...
To build a symmetrical circuit, the substrate of silicon dioxide is considered as a portion of a lossless transmission line on both sides of the band-stop filter. When current is produced in the conductors by the incoming electromagnetic waves, the metallic components show an inductive effect (L...
(Supplementary NoteS1), the reflection spectrum of a DBR with three Si/air layers is calculated, as shown by the gray solid line in Fig.1b. The DBR reflects up to 100% in the band from 0.5 to 0.8 THz. A spectrally wide stop band filter is realized just by three Si/air layers...

We first present the results of two-port band-pass filter structures, and examine experimentally the effect of the size of the structure, number of pixels, and the results with different optimization algorithms, such as genetic algorithm (GA) and binary particle swam optimization (BPSO). Size ...
Consequently, a dynamic band-stop filter range up to 0.56 THz was achieved. In the second method, materials intrinsic features are used to adjust THz waves. Some materials in nature have varying permittivity or permeability based on external situations such as heat, electricity, magnetism, and ...
