Rectangular waveguide.

Circular waveguide.

Elliptical waveguide.

Single-ridged waveguide.

Double-ridged waveguide.

Answer 2

Impedance matching devices for waveguide​ is  Irises.

Explanation:

• The wave guide is guide for mismatch between the wave guide and load. The matching device is called as Irises, which is introduced in to wave guide.

• The iris places a "shunt inductive reactance" across the waveguide which is proportional to the "size of the opening".

• Notice that the "edges of the inductive Irises" are perpendicular to the "magnetic plane".

• The shunt capacitive reactance acts the same way. Again, the "reactance" is proportional to the "size of the opening" but the "edges of the Irises" are perpendicular to the "electric plane" and forms an "equivalent parallel-LC circuit" across the waveguide.
