EDGE TREATMENT SYSTEM AND METHOD FOR EVALUATING A MATERIAL
First Claim
1. A system for treating an edge of a material under test to reduce a propagation of a first electromagnetic wave impinging upon said edge of said material under test, comprising:
- a first substrate having a first edge disposed in between said edge of said material under test and a propagation path of said first electromagnetic wave, wherein said first edge of said first substrate partly overlaps said material under test, such that a first area of said first substrate overlaps a first area of said material under test and a second area of said first substrate extends outwards from said first area of said first substrate overlapping said first area of said material under test and beyond a projected line of said edge of said material under test onto said first substrate, and wherein said first substrate is physically structured to reduce said propagation of said first electromagnetic wave by a sufficient extent so as to enable detection of a second electromagnetic wave of interest that may propagate through said material under test by mitigating an interference to said detection of said second electromagnetic wave caused by an interaction of said first electromagnetic wave and said edge of said material under test.

Abstract
Disclosed is an improved system and method to treat an edge of a material for determining a property of such material through measurements of electromagnetic waves. The system and method are operative to mitigate the adverse effects caused by the interaction between an electromagnetic wave and an edge of a sample of a material under test. The system and method define a configuration to block and significantly attenuate the propagation of electromagnetic waves that may reach an edge of the sample being evaluated. This configuration reduces the undesired effects caused by edge-diffraction that may interfere with the measurement of desired electromagnetic waves for material evaluation. As a result, a property of a material under test can be measured more accurately, especially near the edges of such material. In addition, the system and method enable the evaluation of a small-size sample of a material.

-
a. providing at least a first substrate having a first edge disposed in between said edge of said material under test and a propagation path of said first electromagnetic wave, wherein said first edge of said first substrate partly overlaps said material under test, such that a first area of said first substrate overlaps a first area of said material under test and a second area of said first substrate extends outwards of said first area of said first substrate overlapping said first area of said material under test and beyond a projected line of said edge of said material under test onto said first substrate, and wherein said first substrate is physically structured to reduce said propagation of said first electromagnetic wave by a sufficient extent so as to enable detection of a second electromagnetic wave of interest that may propagate through said material under test by mitigating an interference to said detection of said second electromagnetic wave caused by an interaction of said first electromagnetic wave and said edge of said material under test; b. setting up a sample of said material under test by positioning said sample on a mounting structure located in between a transmit antenna that transmits said second electromagnetic wave and a receive antenna intended to only receive said second electromagnetic wave that may propagate through said material under test; c. determining a scanning area of said sample of said material under test; d. identifying a “
compromised”

compromised”
area; andf. setting up said system configuration of said first substrate on said “
