Abstract
A non-reciprocal microwave network is provided that includes an in-line ferromagnetic element [1010] with adjoining polarizing adapters [1002, 1004, 1006, 1008] to achieve directivity via a multi-mode interaction at or near the ferrite to act as new class of 4-port circulator or 2-port isolator, with standard waveguide inputs for assembly in larger networks.
Claims14
A microwave non-reciprocal network device comprising:
- a source waveguide capable of supporting multiple input/output modes;
- a target waveguide capable of supporting multiple input/output modes;
- an inline non-reciprocal network connected to the source waveguide and the target waveguide and comprising a non-reciprocal media element;
- wherein the inline non-reciprocal network is tuned such that each of multiple linearly polarized input modes couples equally into supported modes of the source and target waveguide moving forward and backward,
- wherein the inline non-reciprocal network is adapted to cancel the forward or backward waves depending on a relative phase difference between two or more orthogonal input signals to the network.
