摘要： The present disclosure provides a method of protecting a component using a deliberately created impedance mismatch between conductive impedance transition elements and an electric power line. The method comprises coupling a plurality of conductive impedance transition elements having a greater diameter than the power line at a position between an extended length of the power line and the component. The difference between the diameters of the conductive transition elements and the power line causes an intentional impedance mismatch between the two or more impedance transition elements with adjacent portions of the power line, and the mismatch causes high-frequency components of the transient electromagnetic signals induced on the power line by the transient electrical disturbance to be reflected by at least one of two or more impedance transition elements away from the protected component.

摘要： Disclosed are a transmission system and a device of small scale, low cost and low power for transmitting signal of a rate over 1 Gbps using a small scale and low loss ultrawide band pass filter (UWBPF). The transmission system comprises the steps of generating pulse signal by a short pulse generator, band-limiting the pulse signal by passing it through a waveshape forming filter, and transmitting the resulting pulse signal in a certain frequency band through a UWBPF, and receiving and passing the signal wave through a UWBPF of the same frequency range and introducing the signal wave through a pulse detector into the determining part. The UWBPF used is prepared by forming a distribution constant circuit on a lossy substrate having low-pass function.

摘要： In a ferrite switchable microwave device, a magnetic structure is formed in a nearly continuous closed-loop configuration of a single crystal material, or of a material exhibiting the magnetic properties of single crystal materials (quasi-single crystal materials). A magnetization M is induced in the structure. The toroidal shape of the structure in combination with the properties of the magnetic material results in a device which exhibits virtually no hysteresis. The device is operable either in a fully magnetized state or in a partially magnetized state. In a fully magnetized state, the device operates in the region of magnetic saturation. The absence of hysteresis in the device enables switching between the positive and negative magnetic saturation points with very little energy. In a partially magnetized state, the device provides a variable magnetization M between the two saturation points. The magnetization curve is made linear and therefore controllable by introducing a gap or other demagnetizing feature in the magnetic structure. This device is particularly operable as a variable phase shifter or tunable filter where the magnetization controls the velocity of electromagnetic energy propagating in the magnetic device.

摘要： A magnetostatic wave device includes a dielectric substrate. Micro strip lines as transducers are formed by forming a ground electrode and strip-line electrodes, on both surfaces of the dielectric substrate. A ferrimagnetic base material formed with a GGG substrate and a YIG thin film on the GGG substrate is arranged on the strip-line electrodes. The ferrimagnetic base material is formed so that the end portions slant from the strip-line electrodes outwardly. The length of the ferrimagnetic base material is established to provide a minimum value.
