The nanostructured material of the metal–insulator–metal (MIM) grating with localized magnetic enhanced is designed by the inductor and capacitor (LC) circuit model. It’s shown that the electromagnetic field can greatly be enhanced when the magnetically resonance is excited. The characteristics of the localized magnetic resonance are discussed. Furthermore, the LC circuit model can be easily used to design the MIM grating for localized magnetic resonance. The geometry parameters predicted by LC circuit model match well with the results simulated by rigorous coupled-wave analysis method.

RF characteristics of metal-insulator-metal (MIM) capacitors with SiO2/HfO2/SiO2 (SHS) were investigated using an equivalent circuit model that is associated with the main impedance ZMIM.cap and the substrate-related conductance Ysub. However, the parasitic capacitance in Ysub was lower than that of another element component in ZMIM.cap, which makes difficult for accurate RF modeling because the parasitic component was dominant at high frequency regions. As low parasitic component is eliminated from the modeling, the extracted capacitance for SHS MIM capacitor was stable up to 20 GHz. The Q-factor and resonant frequency (fr) point of SHS structure are 23.9 at 1 GHz and 9.76 GHz, respectively.

The four polarisation method is adopted for measurement of molecular orientation in dielectric nanolayers of metal-insulator-metal (MIM) metamaterials composed of gold nanodisks on polyimide and gold films. Hyperspectral mapping at the chemical finger printing spectral range of 4–20 μμm was carried out for MIM patterns of 1–2.5 μμm period (sub-wavelength). Overlay images taken at 0,π4,π2,3π4 orientation angles and subsequent baseline compensation are shown to be critically important for the interpretation of chemical mapping results and reduction of spurious artefacts. Light field enhancement in the 60-nm-thick polyimide (I in MIM) was responsible for strong absorption at the characteristic polyimide bands. Strong absorbance A at narrow IR bands can be used as a thermal emitter (emittance E=1−R), where R is the reflectance and A=1−R−T, where for optically thick samples the transmittance is T=0.

A tunable demultiplexer with three output channels infiltrated by liquid crystal (LC) is presented, which is based on a metal-insulator-metal (MIM) waveguide. The operating frequencies of the three output channels can be tuned simultaneously at will by changing the external bias electric field applied to the LC. By analyzing the Fabry-Pérot (FP) resonance modes of the finite-length MIM waveguide both theoretically and numerically, the locations of the three channels are delicately determined to achieve the best demultiplexing effects. Terahertz (THz) signals input from the main channel can be demultiplexed by channels 1, 2 and 3 at 0.7135 THz, 1.068 THz and 1.429 THz, respectively. By applying an external electric field to alter the tilt angle of the infiltrating LC material, the operating frequencies of channels 1, 2 and 3 can be relatively shifted up to 12.3%, 9.6% and 9.7%, respectively. The designed demultiplexer can not only provide a flexible means to demultiplex signals but also tune operating bands of output channels at the same time.
