摘要： An ignition device is provided, the ignition device comprises a coaxial structural body comprising an inner conductor 2, an outer conductor 3, and an insulator 4 that insulates both the conductors 2 and 3, which are coaxially provided with one another along an axial direction. A connection terminal 5 is arranged at one axial end side of the coaxial structural body and connecting the inner conductor 2 and the outer conductor 3 to the electromagnetic wave oscillator MW. The inner conductor 2 has a linearly extended part protruding at another axial end side of the coaxial structural body extending outwards from the outer conductor 3 in the axial direction and a spirally extended part continuously extending from the linearly extended part in a reversed direction and in a spiral manner that winds around the linearly extended part of the inner conductor 2 in a predetermined number of turns around the linearly extended part such that the inner conductor 2 forms a resonance structure and the spirally extended part 20 with the resonance structure is obtained. A diameter and a length of the inner conductor 2 that is extended outwards from the outer conductor 3, and the number of turns of the spirally extended part of the inner conductor 2 are determined such that a capacitive reactance XC and an inductive reactance XL of the spirally extended part are substantially equal to each other.

摘要： To provide an ignition plug having low power loss even though iron is a main component of a center electrode thereof, to which a high frequency power such as a microwave is electrically supplied. A low impedance layer 6 composed of a material having magnetic permeability lower than iron is provided between an outer peripheral surface of a center electrode 2 and an inner peripheral surface of an axial hole 30 of an insulator 3. The low impedance layer 6 is in contact with at least the outer peripheral surface (surface) of the center electrode 2, thereby reducing power loss of an electromagnetic wave flowing on the surface of the center electrode 2. More particularly, the low impedance layer 6 is made of silver, copper, gold, aluminum, tungsten, molybdenum, titanium, zirconium, niobium, tantalum, bismuth, palladium, lead, tin, an alloy composed mainly of these metals, or a composite material of these metals.

摘要： An electromagnetic wave oscillation device includes: a buck-boost circuit having buck-boosters and switching elements; an electromagnetic wave oscillator; an amplifier to amplify an electromagnetic wave and supply an amplified electromagnetic wave to a resistive part; a detector to detect a reflected wave from the resistive part; and a controller to send to one of the switching elements an operation signal in predetermined order, synchronizing with an oscillation timing of the electromagnetic wave oscillator, to output a current from the corresponding buck-boosters to the amplifier in a non-smooth manner. When a detected value of the reflected wave exceeds a predetermined value upon said current output by operating the one of the switching elements, the controller stops sending the operation signal to one or more of the other switching elements that are supposed to output the current after said current output by operating the one of the switching elements.

摘要： In a plasma device 30 that emits an electromagnetic wave to a combustion chamber 10 of an engine 20 so as to generate electromagnetic wave plasma thereby igniting mixture gas, fuel efficiency for lean burn mixture combustion of an engine 20 is improved. During a flame propagation after the mixture gas is ignited in the combustion chamber, the electromagnetic wave is emitted to the combustion chamber 10 so that electrons in a propagating flame resonate with the electromagnetic wave. The resonance between the electrons in the propagating flame and the electromagnetic wave increases flame propagation speed.
