Your task is to investigate whether the tumor may be safely detected

by testing using electromagnetic waves. You may assume that:

(i)

(ii)

the tumor has grown to a thickness of between 5 mm

and 12 mm.

You have been granted permission to carry out low

power (in vitro) laboratory tests in the frequency band

between 1 GHz and 12 GHz in a shielded room. The

power limit is 1 W throughout the allowed frequency

band.

(iii) VSWR, return loss (S11) and input impedance (real and

imaginary part) can all be automatically measured and

that detection of the tumor will be based on those

measurements.

Include in your report:

(a) Your opinion on how electromagnetic waves in the above

frequency range may best assist in safely detecting

malignant tumors with the characteristics described above.

(b) Simulation results specifically chosen to support your

opinion in (a) above.

(c) Statements that logically align your opinion in (a) above

with the simulation results you provide in (b). [You will be

penalised if you provide simulation results with no

corresponding statements that align them with your opinion

in (a)].

(d) Additional simulations that you would do, to confirm your

opinion in (a) above, if the limitations imposed by the

student version of HFSS were to be removed.
