This invention discloses a sensor for detecting ice, water, and dryness states, comprising a substrate, a first metal line, a second metal line, a third metal line disposed on the surface of the substrate, a variable capacitor, an interdigitated capacitor, and a planar inductor. One end of the variable capacitor is connected to one end of the planar inductor via the first metal line, and the other end of the planar inductor is connected to one end of the interdigitated capacitor via the second metal line. The other end of the interdigitated capacitor is connected to the other end of the variable capacitor via the third metal line. The capacitance value of the interdigitated capacitor changes with the different dielectric constants of the materials between the interdigitated fingers. Since the relative dielectric constants of ice, water, and dryness change at different frequencies, the capacitance value of the interdigitated capacitor also changes. Therefore, this sensor for detecting ice, water, and dryness states has advantages such as simple structure, high recognition rate, small size, and process compatibility.

The application discloses a Jerusalem unit double-layer FSS broadband wave-absorbing structure and a preparation method and application thereof, and belongs to the field of electromagnetic wave-absorbing technology design in electromagnetic stealth technology. The structure is sequentially arranged from bottom to top as a metal bottom layer, a dielectric layer 1, a patterned resistance layer 1, a dielectric layer 2 and a patterned resistance layer 2. Periodic array distributed multiple unit cell structures are formed on the surfaces of the patterned resistance layer 1 and the patterned resistance layer 2, and each unit cell structure adopts a Jerusalem cross pattern. The Jerusalem unit double-layer FSS broadband wave-absorbing structure provided by the application has a wide-frequency absorption characteristic.

This invention discloses a small, equal-band dual-frequency transceiver based on wireless communication technology. It includes a ceramic dielectric body, a tuning element, a multilayer circuit body, and an external electrode assembly. The tuning element is disposed on top of the ceramic dielectric body. The multilayer circuit body is disposed inside the ceramic dielectric body and electrically connected to the tuning element through a via structure. The multilayer circuit body includes a low-frequency channel filter and a high-frequency channel filter. The external electrode assembly is disposed at the bottom of the ceramic dielectric body. The low-frequency channel filter outputs signals within a set low-frequency band, and the high-frequency channel filter outputs signals within a set high-frequency band. This invention achieves a large capacitance value within a small volume by using vertical coupling. By setting the tuning element, the stopband bandwidth and suppression depth of the dual-frequency transceiver can be flexibly adjusted by changing the value of the tuning element, resulting in miniaturization, wide stopband, high suppression, and tunability.

This invention provides a snapshot-type Fourier transform Stokes polarization imaging spectrometer, comprising, in sequence along the beam propagation direction: a telescope system, a polarization modulation system, a converging system, a polarization interferometer system, and an imaging system. A target light field emitted from a target scene is incident on the telescope system. After passing through the telescope system, the target light field is collimated into a parallel light field and incident on the polarization modulation system. The parallel light field passes through the polarization modulation system sequentially to obtain a linearly polarized light field, which is then incident on the converging system. The converging system is used to perform multi-array imaging of the linearly polarized light field, resulting in multiple imaging light fields that are incident on the polarization interferometer system. The multiple imaging light fields generate superimposed interference at the light exit position of the polarization interferometer system, forming a polarization interferometric image field with specific optical path difference distribution characteristics. This image field is then incident on the imaging system to obtain an interferometric image array. Based on the aforementioned interferometric image array, the spectral information of each Stokes parameter of the target light field under each field of view is demodulated.
