Anechoic chamber absorber and method

A method of making an anechoic chamber absorber comprising the following steps:

• selecting sheets of material each including lossy material and having first and second edges defining a length and a height;
• creating a block of honeycomb material from the sheets of material;
• and
• creating wedges of lossy material within the block of honeycomb material, said block of honeycomb material having an T-direction and a L-direction, corresponding to the height and length of the sheets of material, and a W-direction.

A method of making an anechoic chamber absorber comprising the following steps:

• selecting sheets of material each having first and second edges defining a length and a height;
• applying a lossy material to the sheets of material in a repeating wedge-shaped pattern, said wedge-shaped pattern including periodic wedge-shaped units extending along the length of the sheets of material, the wedge-shaped units having narrow tip portions facing the first edge and broadened base portions facing the second edge;
• periodically increasing and decreasing the heights of the wedge-shaped units applied to successive ones of the sheets of material;
• and
• creating a block of honeycomb material from the sheets of material with said lossy material applied in the wedge-shaped pattern thereby creating pyramids of lossy material within the block of honeycomb material.
