electrets with lobar patterns?

 

Hi there -
i was wondering if there are electret elements with lobar patterns. i'm not seeing any on a simple google search - and i'm curious about why that might be.?

Thanks!

 

I suspect the lobar pattern comes more from the interference tube, not the capsule itself.

(I¡¯m definitely not an expert on shotgun mic design¡­ but if it were possible to create a lobar pattern within the capsule, then all those shotgun mics wouldn¡¯t need to be 6-20 inches long.)

Microphones with "lobar" patterns use specific acoustic additions to achieve them. Typically multiple tubes or multiple tapped tubes. Capsules by themselves are 1st-order, ranging from omni to fig-8 via all sorts of cardio.
Higher order directivity can also be achieved using multiple capsules and signal processing.
