Abstract
There is provided a device arranged to couple electromagnetic radiation into or out of a biological material. The device comprises a first metamaterial comprising: a substrate component having a thickness no greater than a first wavelength of the electromagnetic radiation; and a plurality of elements supported by the substrate component, wherein each element has a first dimension no greater than a first wavelength of the electromagnetic radiation and at least two of the elements of the plurality of elements are non-identical.

A sensor measurement device, comprising:
- a first antenna configured to generate electromagnetic radiation to penetrate a biological material, the electromagnetic radiation having a first wavelength;
- a first anti-reflection device, positioned between the first antenna and the biological material, to transmit electromagnetic radiation of the first wavelength emitted by the first antenna into the biological material, the first anti-reflection device comprising a first metamaterial comprising:
- a substrate component having a thickness no greater than the first wavelength of the electromagnetic radiation;
- and
- a plurality of elements supported by the substrate component, wherein the plurality of elements are spaced apart from one another across the substrate component, wherein each element has a first dimension no greater than the first wavelength of the electromagnetic radiation and wherein at least two elements of the plurality of elements differ in shape and/or size;
- and
- a second antenna configured to receive electromagnetic radiation from the biological material, wherein the first antenna and the second antenna are arranged such that the biological material is positioned in a radiation path between the first antenna and the second antenna, and wherein the first antenna, the first anti-reflection device, and the second antenna are physically associated.
A method of coupling electromagnetic radiation into a biological material using a sensor measurement device, the sensor measurement device comprising:
- a first antenna configured to generate electromagnetic radiation to penetrate a biological material, the electromagnetic radiation having a first wavelength;
- a first anti-reflection device, positioned between the first antenna and the biological material, to transmit electromagnetic radiation of the first wavelength emitted by the first antenna into the biological material, the first anti-reflection device comprising a first metamaterial comprising:
- a substrate component having a thickness no greater than the first wavelength of the electromagnetic radiation;
- and
- a plurality of elements supported by the substrate component, wherein the plurality of elements are spaced apart from one another across the substrate component, wherein each element has a first dimension no greater than the first wavelength of the electromagnetic radiation and wherein at least two elements of the plurality of elements differ in shape and/or size;
- and
- a second antenna configured to receive electromagnetic radiation from the biological material, wherein the sensor measurement device is a single unit physically associating together the first antenna, the first anti-reflection device, and the second antenna,
- the method comprising:
- positioning the sensor measurement device with respect to the biological material such that the first antenna is disposed on a first side of the biological material and the second antenna is disposed on a second side of the biological material;
- providing electromagnetic radiation having the first wavelength from the first antenna to the first anti-reflection device;
- transmitting, by the first anti-reflection device, electromagnetic radiation having the first wavelength from the first antenna into the biological material;
- receiving, by the second antenna, electromagnetic radiation from the biological material;
- and
- characterizing the biological material based on the received electromagnetic radiation.
