A microwave load is produced with a relatively absorbent metal cylinder closed at its ends by reflecting shutters.

A microwave applicator including a generally cylindrical microwave containment chamber, a microwave energy source, and a feed structure connecting the microwave energy source to the containment chamber.

An assembly for applying microwave irradiation to a load having a generally circular cross section.

The microwave structure provides at an output a hyperfrequency wave.

The invention further relates to a method for production of such a material and is of application to hyper-frequency circulators.

A low power microwave receiver (70) receives a reflected microwave signal.

The microwave resonant cavity (1) is also connected with a microwave input source (3).

A microwave integrated circuit chip (10) having microwave transmission line (32) coupled to an input of microwave circuitry (60) when the microwave circuitry has capacitive input impedance.

The method includes establishing microwave energy in the cavity and monitoring changes in the cavity microwave response, the changes being related to filter loading.

The invention relates to a device for detecting objects, that comprises at least one hyper-frequency transmitter (2) and one hyper-frequency receiver (1).

The channel is preferably filled with objects that acquire an electrostatic charge when irradiated with a microwave field.

The invention concerns a microwave resonant circuit and a tunable microwave filter using said resonant circuit.

A platform is provided for the manufacture of microwave, multilayer integrated circuits and microwave, multifunction modules.

A microwave load is produced with a relatively absorbent metal cylinder closed at its ends by reflecting shutters.

Means such as a microwave transparent tube or conveyor provide for positioning of the load in the applicator.
