Abstract: Sensing waveguides with non-rectangular cross-section are transformed to rectangular ones by means of conformal mapping.The electric field,magnetic field,critical frequency,surface current, power transmission and attenuation,as well as TE and TM modes in waveguides are discussed.Numerical results of four sensing waveguides with non-rectangular cross-section are given.

Key words: conformal mapping, non-rectangular cross-section sensing waveguides, TE wave, TM wave
