  • Publication number: 20210199428
    Abstract: The present disclosure relates to a device and a method for measuring a thickness of an ultrathin film on a solid substrate. The thickness of the target ultrathin film is measured from the intensity of the fluorescence converted by the substrate and leaking and tunneling through the target ultrathin film at low detection angle. The fluorescence generated from the substrate has sufficient and stable high intensity, and therefore can provide fluorescence signal strong enough to make the measurement performed rapidly and precisely. The detection angle is small, and therefore the noise ratio is low, and efficiency of thickness measurement according to the method disclosed herein is high. The thickness measurement method can be applied into In-line product measurement without using standard sample, and therefore the thickness of the product can be measured rapidly and efficiently.

  • Publication number: 20210167483
    Abstract: A dual-mode dielectric resonator using two dissimilar modes is described, the dissimilar modes supported by a ridge waveguide resonator and a ¼-wavelength (¼?) metalized cylindrical resonator within a single, metal-coated dielectric block. Each ridge waveguide resonator and cylindrical resonator form a dual-mode resonator pair. Coupling control posts set between the ridge waveguide resonator and cylindrical resonator can adjust their coupling. Multiple pairs of ridge waveguide/cylindrical resonators are fabricated in the same dielectric block to form a coupled resonator bandpass filter, including an 8-pole or 10-pole dielectric resonator filter, for 5G or other applications. Transmission zeros can be introduced by a metalized blind hole extending vertically between two ridge waveguide resonators or a microstrip extending between two dual-mode resonator pairs between which there exists no partial-width or full-width dielectric window.

  • Publication number: 20210109042
    Abstract: This disclosure relates to an apparatus and methods for applying X-ray reflectometry (XRR) in characterizing three dimensional nanostructures supported on a flat substrate with a miniscule sampling area and a thickness in nanometers. In particular, this disclosure is targeted for addressing the difficulties encountered when XRR is applied to samples with intricate nanostructures along all three directions, e.g. arrays of nanostructured poles or shafts. Convergent X-ray with long wavelength, greater than that from a copper anode of 0.154 nm and less than twice of the characteristic dimensions along the film thickness direction, is preferably used with appropriate collimations on both incident and detection arms to enable the XRR for measurements of samples with limited sample area and scattering volumes.

  • Publication number: 20200407683
    Abstract: The present invention relates to an in vitro immune synapse system and a method of in vitro evaluating immune response using the same. The in vitro immune synapse system includes antigen-presenting cells (APCs) and at least one cell type of several specific T cell subtypes isolated from peripheral blood mononuclear cells (PBMCs), all of which is from a same individual of pigs. When a test sample is co-cultured in the in vitro immune synapse system for a given period, it can be determined that the test sample is immunogenic, immunostimulatory or not according to the immunization-related changes of these cells, thereby potentially replacing some kinds of animal experimentation.
