Abstract: A platform able to vary a plasma resonance frequency applies to a prism of a conventional surface plasma resonance system and comprises at least one platform and a plurality of metal lines. The platform is a plate-like structure having two faces—a detection face and a connection face. The metal lines are arranged on the detection face. Each metal line has a width of 20-500nm and a thickness of 20-100nm. The spacing between two adjacent metal lines is 50-1000nm. The prism of the conventional surface plasma resonance technology is an application of the refraction technology. The optical grating technology is another application of the diffraction technology. However, the present invention is different from the abovementioned two technologies. The present invention increases the wavelength range of the absorption spectrum to the mid-infrared ray to promote the detection application of the surface plasma resonance technology.

Abstract: A dielectric resonator for a negative refractivity medium, which is coupled to a plurality of substrates, comprises at least one crystal unit, at least one first crystal cube and at least one second crystal cube. The crystal units are arrayed on the substrate. On an identical substrate, each crystal unit has a first spacing with respect to one adjacent crystal unit and a second spacing with respect to another adjacent crystal unit. The first spacing is vertical to the second spacing. Each crystal unit has one first crystal cube and one second crystal cube. A third spacing exists between the first and second crystal cubes. The first and second crystal cubes have a permittivity greater than 20. The present invention adopts the negative refractivity medium to achieve lower dielectric loss. Further, the present invention features isotropy and has low fabrication cost and high industrial utility.

Abstract: The present invention discloses a structure and method for realizing electromagnetically-induced transparency. In the present invention, a first split-ring resonator and a second split-ring resonator form a resonance structure. The first split-ring resonator and the second split-ring resonator are made of a conductive material. The first split-ring resonator has a “U” shape with a containing space. The second split-ring resonator has a “rectangular loop” shape with a gap or has a “U” shape with an opening. The second split-ring resonator is inserted into the containing space with the gap or opening arranged inside the containing space and faced downward to form the resonance structure. The resonance structures are periodically arranged on a chip to form an array. Thereby, different-frequency electromagnetic waves can be used to generate electromagnetically-induced transparency via regulating the dimensions of the resonance structure.

Abstract: The present invention discloses a visualized plasmon resonance biodetector, which utilizes the surface plasmon resonance to detect a plurality of biochemical molecules, and which comprises a substrate, a silver-gold dual-layer structure, and a visible light source. The silver-gold dual-layer structure is formed on the substrate. In a test, a biochemical molecule combines with the silver-gold dual-layer structure, and the visible light source emits a visible light to illuminate the substrate. Thus, the silver-gold dual-layer structure on the substrate generates surface plasmon resonance and a reflected light. The user can use his naked eyes to discriminate the reflected lights and learn the component and concentration of the biochemical molecule. Therefore, the present invention can provide a low-cost and easy-to-operate detection instrument for biotests.

Abstract: A plane focus antenna includes a plurality of stacking substrates. Each substrate has one side formed a periodic array plane consisting of a plurality of resonant coils and other side laid a metal wire formed in a periodic structure. The magnetic permeability of the stacking double split-ring resonators is negative and the electric permittivity of the metal wire is negative at the same time that can interact with electromagnetic waves to fabricate a negative refractive index material (NRIM) to form the plane focus antenna. By means of the special refractive effect of the NRIM receiving signals can be converged in a very small area to enhance the receiving signals. The plane antenna also does not generate distortion.

Abstract: A man-made magnetic material presenting magnetic response at different frequencies is made from non-magnetic conductive metal and formed in a four-way symmetrical structure consisting of four L-shaped units. A plurality of the four-way symmetrical structures is arranged to form a periodic array. The four-way symmetrical structure is formed at a size much smaller than the wavelength of incident light. Hence it is treated as an effective uniform medium in terms of the incident light. Such a novel planar structure can generate magnetic response in a wide range of bandwidth. The frequency band capable of generating the magnetic response also can be regulated and altered through control of the structural size.

Abstract: The present invention discloses a planar surface plasmon resonance detector, wherein a periodic metallic grating structure is arranged on a common glass substrate to replace prisms and generate surface plasmon resonance. The shift of the wavelength or incident angle for surface plasmon resonance is used to detect biochemical molecules. Further, a low-cost white light-emitting diode replaces laser to function as a light source. Via the metallic grating structure and the white light-emitting diode, the present invention can facilitate a low-cost, compact and portable planar surface plasmon resonance detector and popularize the planar surface plasmon resonance detector.

Abstract: The present invention discloses a plasma reflective polarizer, which comprises a transparent substrate and a metal-line film. The metal-line film is formed via periodically disposing metal lines on the transparent substrate. Alternatively, the plasma reflective polarizer of the present invention comprises a plurality of transparent substrates stacked one above one; each transparent substrate has a metal-line film, and the metal-line film is formed via periodically disposing metal lines on the transparent substrate. The plasma reflective polarizer of the present invention is a simple structure formed of only a common transparent substrate and a metal-line film. Therefore, the present invention is a low-cost plasma reflective polarizer having a high brightness-enhancing function and superior mechanical properties.
