1. A probe comprising:
- a support member;
a transmit antenna disposed towards an end of the support member;
a receive antenna disposed adjacent the transmit antenna; and
a signal barrier disposed on the support member between the transmit antenna and the receive antenna so as to force signals traveling from the transmit antenna to the receive antenna to propagate through a surrounding region.

Abstract
A probe for obtaining a measure of one or more properties in a sample wherein the probe comprises a support member (2), a transmit antenna (4), a receive antenna (5) and a signal barrier (6). The signal barrier (6) is located between the transmit antenna (4) and the receive antenna (5) in order to force signals traveling between transmit antenna (4) and receive antenna (5) to propagate into the surrounding region. Modification of the microwave signal after it passes through the surrounding region is measured and used to infer one or more properties of the test material.
