摘要： Terahertz metamaterials comprise a periodic array of resonator elements disposed on a dielectric substrate or thin membrane, wherein the resonator elements have a structure that provides a tunable magnetic permeability or a tunable electric permittivity for incident electromagnetic radiation at a frequency greater than about 100 GHz and the periodic array has a lattice constant that is smaller than the wavelength of the incident electromagnetic radiation. Microfabricated metamaterials exhibit lower losses and can be assembled into three-dimensional structures that enable full coupling of incident electromagnetic terahertz radiation in two or three orthogonal directions. Furthermore, polarization sensitive and insensitive metamaterials at terahertz frequencies can enable new devices and applications.

摘要： A circuit substrate has three wiring layers, wherein a signal line is formed in a first wiring layer; a ground plane is formed in a second wiring layer; a resonant line is formed in a third wiring layer. A circumferential slit is formed in the ground plane, wherein an island electrode separated from the ground plane is formed inside the slit. The left end of the resonant line is connected to the island electrode through an interlayer-connecting via, while the right end of the resonant line is connected to the ground plane through an interlayer-connecting via. A transmission line (or a microstrip line) is formed using the signal line and the ground plane, and therefore a complex resonator is formed to embrace the transmission line. This achieves band elimination with regard to a signal component of a resonance frequency among signals propagating through the microstrip line. Thus, it is possible to form a noise suppression structure without mounting additional parts on the circuit substrate, and therefore it is possible to effectively eliminate power distribution noise and noise propagating through the signal line with a small and simple configuration.
摘要翻译：电路基板具有三个布线层，其中信号线形成在第一布线层中; 在第二布线层中形成接地平面; 在第三布线层中形成谐振线。在接地平面内形成有周向狭缝，在狭缝内部形成有与接地面分离的岛状电极。谐振线路的左端通过层间连接通孔连接到岛状电极，而谐振线路的右端通过层间连接通孔连接到接地层。使用信号线和接地层形成传输线（或微带线），因此形成复数谐振器以包围传输线。这实现了通过微带线传播的信号中的谐振频率的信号分量的频带消除。因此，可以形成噪声抑制结构而不在电路基板上安装附加部件，因此可以以简单的结构有效地消除通过信号线传播的功率分配噪声和噪声。

摘要： A transmission line resonator includes a half-wavelength stepped-impedance resonator with two ends short-circuited to ground, and a capacitive element with one end connected to a center portion of the stepped-impedance resonator and the other end short-circuited to ground. The stepped-impedance resonator includes a first transmission line, a second transmission line, and a third transmission line. The second transmission line has a second line impedance and a second line length, with one end being connected to one end of the first transmission line and the other end being short-circuited to ground. The third transmission line has the second line impedance and the second line length, with one end being connected to the other end of the first transmission line and the other end being short-circuited to ground. The first line impedance is lowered in comparison with the second line impedance.

摘要： Provided is a line filter. The line filter includes a plurality of dielectric layers stacked one another, a plurality of line resonator each comprising transmission lines on at least two of the dielectric layers, and a tuning unit adjusting a binding amount and resonance frequency of the line resonators. Since the line filter includes at least one line resonator on at least two stacked dielectric layers, the integration can be easily realized. Further, since the line filter can be adjusted even after the line filter is manufacture, the line filter has an excellent frequency property. Since the line filter is realized on the plurality of the dielectric layers, the frequency band can be widened.
