Patent ID: 6867664

Claim:
A waveguide phase shifter device for use in delaying or accelerating an electromagnetic signal, the device comprising: a completely filled elongated section of said device, said section being predefined and completely filled with a magnetic material; enclosure means for preventing said signal from radiating through top, bottom, and parallel side portions of said section, said enclosure means enclosing said top, bottom and side portions of said section and thereby guiding said signal in a predefined direction of propagation; at least one magnetic means for creating at least one magnetic field in said section, said at least one magnetic field resulting in first magnetic field components in a first direction transverse to said predefined direction of propagation and parallel to a line dividing a cross-sectional area of said section into substantially equal areas and parallel to said parallel side portions of said section; wherein said at least one magnetic field further results in second magnetic field components in a second direction parallel and opposite to said first magnetic field components.
