the function of a diode detector is to detect stuff
a: its function is to detect a change of light withing its perimeter
Horn antenna are typically fed by a section of a waveguide, the waveguide itself is often fed with a short dipole.

It replaces a coax cable, which won't work at those frequencies.
Detector converts optical signal to electric signal
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;

Turn off power to the area where the smoke detector will be installed. Remove the old smoke detector, if applicable. Connect the new smoke detector to the existing wiring. Mount the smoke detector on the ceiling or wall using screws. Restore power and test the smoke detector to ensure it is functioning properly.
Moisture in the air in a waveguide can scatter the microwave energy the waveguide is designed to transport. This translates into signal loss or attenuation. The VSWR drops, and that is not a good thing.
If your smoke detector is indicating a low battery, you should replace the battery immediately to ensure that the detector continues to function properly and provide early warning in case of a fire.
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
The discriminator, and the ratio detector, perform the same function in an f.m. receiver as the detector does in an a.m. receiver, i.e. it recovers the modulation.
The waves that cannot be transmitted in a waveguide are those that have a wavelength longer than the cutoff wavelength of the waveguide. These waves are unable to propagate efficiently within the waveguide due to the cutoff phenomenon which restricts their transmission.
If your smoke detector is beeping due to a low battery, you should replace the battery immediately to ensure the detector continues to function properly and keep your home safe from potential fires.
